How do you find the indicated term of a geometric sequence? Find the first five terms in this geometric sequence. a_n = 2^{n - 1} Find the first five terms of the geometric sequence given by: a_1 = -486, an = (-
How do we find the sum of a geometric sequence? Discover how to quickly add up the first terms of a geometric sequence in this quick maths article.
Calculate the first term in the sequence using the formula a = t/[f^(n - 1)], in cases where you are given a single number, t, and its position in the sequence, n, as well as the factor. So if the second term in the sequence (at n = 2) is 6 and f = 2, a = 6/[2...
