Question

Complete the recursive formula of the geometric sequence -125,-25,-5,-1

b(1)=
b(n) = b(n-1)•

Answer 1

The recursive formula for the geometric sequence -125, -25, -5, -1 is b(n) = b(n-1) • r, with b(1) = -125.

Step-by-step explanation:

The geometric sequence -125, -25, -5, -1 can be represented by the recursive formula b(n) = b(n-1) • r, where b(1) is the first term and r is the common ratio.

To find b(1), we can see that the first term is -125.

Therefore, b(1) = -125.
