Question

Which formula can be used to find the nth term of the geometric sequence below?

1/6,1,6,36,.......

Answer 1

It's D, luv

Explanation:

an = 1/6·6ⁿ⁻¹

Answer 2

nth term = (1/6)(6)^(n-1).

Explanation:

The first term a1 = 1/6 and the common ratio r = 1 / 1/6 = 6, also 36/6 = 6 which confirms this.

So the nth term = a1 r^(n - 1)

= (1/6) 6^(n-1).
