In a geometric sequence: .

Find the sequence.

how do u use the formula: to find the sequence?

We know the sum of the first 3 terms: .

. . Hence: . .[1]

We know the sum of the first 6 terms: .

. . Hence: . .[2]

Divide [2] by [1]: .

Factor and reduce: .

. . Then: .

Substitute into [1]: .

Therefore, the sequence is: .
