Notice from the table it appears that the sum of the first n terms is the (nth2) term minus 1 We will use mathematical induction to prove that in fact this is the correct formula to determine the sum of the first n terms of the Fibonacci sequence21 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 formula an=4⋅(2)n−1 represents a sequence If n≥1, what are the first three terms in the sequence?

The hypothesis of Step 1) The statement is true for n = k is called the induction assumption, or the induction hypothesis It is what we assume when we prove a theorem by induction Example 1 Prove that the sum of the first n natural numbers is given by this formula 1 2 3 n =2 5 6 10 Note that all these 3 sets are sorted I have to calculate n(n1)/2 for every (ai1ai1) where i is the index of the array and a is the generalized array Also consider corner cases from both ends They are to subtract 1 from first digit and then calculate n(n1)/2 and to subtract last digit from 11 and then calculate n(n1)/2The formula an=4⋅(2)n−1 represents a sequence If n≥1, what are the first three terms in the sequence?

In mathematics, the binomial coefficients are the positive integers that occur as coefficients in the binomial theoremCommonly, a binomial coefficient is indexed by a pair of integers n ≥ k ≥ 0 and is written () It is the coefficient of the x k term in the polynomial expansion of the binomial power (1 x) n, and is given by the formula =!!()!For example, the fourth power of 1 x isComparing to above formula if we want to calculate sum up to n1, using the above formula we get n1 (n11)/2 That is n (n1)/2 Thus the required formula is n (n1)/2 186K viewsFactor n^21 n2 − 1 n 2 1 Rewrite 1 1 as 12 1 2 n2 − 12 n 2 1 2 Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (ab)(a−b) a 2 b 2 = ( a b) ( a b) where a = n a = n and b = 1 b = 1 (n1)(n− 1) ( n 1) ( n 1)
