The buns Kate, Zofia, and Peter Liked buns Even today, their grandmother prepares their favorite meal Katka eats 4 bunches, Žofia 3, and Petra eats 5 buns I am looking for a formula to which I can supply a number N and have it calculate 1234N I realise that I can enter 1 to N in as many cells then use SUM but this won't do for what I need to achieve That means that the total number of compare/swaps you have to do is (n 1) (n 2) This is an arithmetic series, and the equation for the total number of times is (n 1)*n / 2 Example if the size of the list is N = 5, then you do 4 3 2 1 = 10 swaps and notice that 10 is the same as 4 * 5 / 2

Basic Approach If you will solve this question with a very basic approach of finding value of (1 n 2 n 3 n 4 n) and then finding its modulo value for 5, you will certainly get your answer but for the larger value of n we must got wrong answer as you will be unable to store value of (1 n 2 n 3 n 4 n) properly Better and Proper Approach Before proceeding to solutionTap for more steps A mixed number is an addition of its whole and fractional parts Add 5 5 and 1 4 1 4 Tap for more steps To write 5 5 as a fraction with a common denominator, multiply by 4 4 4 4 Combine 5 5 and 4 4 4 4 Combine the numerators overThis series is pretty easy, though each term a n is twice n, so there is clearly a "2n" in the formula I also have the alternating sign If I multiply 2n by (–1) n, then I'll get –2, 4, –6, 8, –10, which is backwards (on the signs) from what I want
For instance, the sequence 5, 7, 9, 11, 13, 15, is an arithmetic progression with a common difference of 2 If the initial term of an arithmetic progression is a 1 {\displaystyle a_{1}} and the common difference of successive members is d , then the n th term of the sequence ( a n {\displaystyle a_{n}} ) is given by(1) 6 (3) 8 (2) 2 (4) 4 69 Which hydrocarbon is a member of the series with the general formula CnH2n–2? 0 1 0 0 1 0 0 0 2 1 1 1 3 2 273 2 2 4 9 1 9 9 5 44
3 children 3 children had to divide 4 pounds is candy How much candy did each child get? Homework Helper 3,798 94 Little ant said 1^2 2^2 3^2 2^n = 2^ (n1) This makes absolutely no sense I mean, look at it for a second firstly you failed to notice the pattern correctly since 2^n means 2^12^22^3 instead of what is shown And secondly, how can that all equal 2^ (n1) when on the left side of the equation, youDivide both sides of the equation by 2 to have 1 as the coefficient of the first term n2n (3/2) = 0 Subtract 3/2 from both side of the equation n2n = 3/2 Now the clever bit Take the coefficient of n , which is 1 , divide by two, giving 1/2 , and finally square it giving 1/4
Question I have been looking at your Excel IF, AND and OR sections and found this very helpful, however I cannot find the right way to write a formula to express if C2 is either 1,2,3,4,5,6,7,8,9 and F2 is F and F3 is either D,F,B,L,R,C then give a value of 1 if not then 0 I have tried many formulas but just can't get it right, can you help(1) "n2" was replaced by "n^2" 1 more similar replacement(s) Rearrange Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation n^3/n^24(5)=0 Step by step solution Step 1 n 3 Simplify —— n 2 Dividing exponential expressions 11 n 3 divided by n 2 = n (3 2) = n 1 = nNotice the first few digits (0,1,1,2,3,5) are the Fibonacci sequence?

What is the sum of $1^4 2^4 3^4 \dots n^4$ and the derivation for that expression using sums $\sum$ and double sums $\sum$$\sum$? Now rearrange them (1 6) (2 5) (3 4) Which is obviously 7 7 7 Which is also 3 * 7 Since you always start with one, you will always get N / 2 "pairs" (the center "pair" will be just a single digit if it's an odd number of terms) 6 / 2 = 3 And you need to include the total of each pair 6 1 = 7 so N / 2 pairs, of N 1 Get an answer for '`1/(2*3) , 1/(3*4), 1/(4*5), 1/(5*6) 1/((n 1)(n 2))` Use mathematical induction to find a formula for the sum of the first n
21 For the proof, we will count the number of dots in T (n) but, instead of summing the numbers 1, 2, 3, etc up to n we will find the total using only one multiplication and one division!The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction 9n^ {2}7n4=0 9 n 2 − 7 n − 4 = 0 This equation is in standard form ax^ {2}bxc=0 Substitute 9 for a, 7 for b, and 4 for c in the quadratic formula, \frac {b±\sqrt {b^ {2}4ac}} {2a}Now, if we subtract the second equation from the first, the 1/2, 1/4, 1/8, etc all cancel, and we get S (1/2)S = 1 which means S/2 = 1 and so S = 2 This same technique can be used to find the sum of any "geometric series", that it, a series where each term is some number r times the previous term

For an AP, the sum of the first n terms can be calculated if the first term and the total terms are known The formula for the arithmetic progression sum is explained below Consider an AP consisting "n" terms S = n/2 2a (n − 1) × d This is the AP sum formula to find the sum of n terms in series Proof Consider an AP consistingTo find the Population Standard deviation of 1,2,3,4,5 Perform the steps 1 and 2 as seen in above example Step 3 Now find the population standard deviation using the formula √10/√5 = 1414 Variance Example To find the Variance of 1,2,3,4,5 After(13) we will prove that the statement must be true for n = k 1 1 5 9 13 4(k 1) 3 = 2(k 1)2 (k 1
