Question

Consider the geometric sequence 4, 40, 400, 4000, ...

Answer 1

Answer:

a(n) = 4*10(n - 1)

Step-by-step explanation:

Each term of the given sequence is 10 times greater than the previous term.

The first term of this sequence is 4.

Thus, the explicit formula desired is:

a(n) = 4*10(n - 1).
