Question

Can you please solve this

this is only 8th grade math

Answer 1

second option: 6

Explanation:

The general term of a geometric sequence is given by:
`a_(n) = a_(1) r^(n-1)`

∴
`a_(1)` is the first term

`a_(8) = a_(1) (3)^(8-1)`

13122 =
`a_(1)`
`(3)^(7)`

13122 =
`a_(1)` x 2187

13122/2187 =
`a_(1)`

6 =
`a_(1)`
