Question

How do you find the first five terms of the geometric sequence `a_1=243`, r=1/3?

Answer 1

`243,81,27,9,3`

Explanation:

The terms in a `color(blue)"geometric sequence"` are.

`a,ar,ar^2,ar^3,......,ar^(n-1)`

To obtain any term in the sequence, multiply the previous term
by r

`a_1=243`

`rArra_2=243xx1/3=81`

`rArra_3=81xx1/3=27`

`rArra_4=27xx1/3=9`

`rArra_5=9xx1/3=3`
