7. Find all geometric sequences such that the sum of the first two terms is 24 and the sum of the first
three terms is 26.

Respuesta :

Answer:

Step-by-step explanation:

Let the first term is n, then the second term must be an where a is a common ratio, and the third term is a^2 n

so, n + an = 24

n + an + a^2 n = 26

solve for a, then solve for n
