Correct Answer

✅ Option c — 64

We are given the series: $4, 16, \dots, 256, 1024

\displaystyle <br>Let's express the given terms as powers of the base

\displaystyle :<br>-

4 = 4^1

\displaystyle <br>- &#36;16 = 4^2

- $256 = 4^4

\displaystyle <br>- &#36;1024 = 4^5

The series follows the pattern

\displaystyle 4^n

for consecutive integers

\displaystyle n = 1, 2, 3, 4, 5

.
Therefore, the missing third term must be

\displaystyle 4^3

4^3 = 64

Hence, **Option C** is the correct answer.
