Question

What is the common raito if geometric sequence shose first term is 27 and fourth term is 64?

Pleaseeee helppp

Answer 1

`(4)/(3)`

Explanation:

1) if the given sequence is geometric one, then the formula of n-term is

`b_n=b_1*q^(n-1);`

2) according to the formula above:

`b_4=b_1*q^3;\\64=27*q^3;= > \\q^3=(64)/(27);\\q=(4)/(3) .`
