Question

Given the first term and the common ratio of a geometric sequence, find the first five terms and write the explicit formula.
a1 = 1, r = ½

Answer 1

just like the last one, except this time \(r=\frac{1}{2}\) instead of \(2\)

Answer 2

first term is 1, second is \(\frac{1}{2}\) third is \(\frac{1}{2}\times \frac{1}{2}=\frac{1}{4}\) and so on

Answer 3

@satellite73 whats the explicit formula, and fourth term is 1/8 and fifth is 1/16

Answer 4

@jim_thompson5910

Answer 5

an = a1 * r^n-1
a1 is the first term
r is the common difference
n is the number of the term you want to find.

Answer 6
