WebFor an arithmetic sequence, the nth term is calculated using the formula s + d x (n - 1). So the 5-th term of a sequence starting with 1 and with a difference (step) of 2, will be: 1 + … WebIf the initial term of an arithmetic sequence is a 1 and the common difference of successive members is d, then the nth term of the sequence is given by: a n = a 1 + (n - 1)d The sum of the first n terms S n of an arithmetic sequence is calculated by the following formula: S n = n (a 1 + a n )/2 = n [2a 1 + (n - 1)d]/2 flight gear md11

How to find the formula for the general term of a sequence

WebFinal answer. Transcribed image text: Find the general term of the sequence, starting with n = 1. Determine whether the sequence converges, and if so find its limit. If the … Web(a geometric sequence). Each successive term is multiplied by 3, so for any term n (where n>=1), its denominator would be 3^(n-1). Then notice that every numerator is 4 less than its denominator, so the formula for the … WebArithmetic sequence formula is: \ (a^n=a^1+ (n-1) d\) ADVERTISEMENT. \ (A^n\) = any nth term in the given sequence. \ (A^1\) = it represents the first term in the given sequenced = it is the common difference that exists among terms. An arithmetic sequence equation can be simplified and found by using this formula. chemistry paper 2 rate of reaction
