Question

2, 4, 8, 16, 32, ...

Explanation:

Step1: Identify sequence pattern

Each term is $2 \times$ prior term.

Step2: Define general formula

$a_n = 2^n$, where $n=1,2,3,...$

Answer:

This is a geometric sequence with the general term $\boldsymbol{a_n = 2^n}$ (the next terms would be 64, 128, etc.)
