Detailed Solution & Explanation

We are given the series: 4,16,…,256,1024\displaystyle 4, 16, \dots, 256, 1024
Let's express the given terms as powers of the base 4\displaystyle 4:
- 4=41\displaystyle 4 = 4^1
- 16=42\displaystyle 16 = 4^2
- 256=44\displaystyle 256 = 4^4
- 1024=45\displaystyle 1024 = 4^5
The series follows the pattern 4n\displaystyle 4^n for consecutive integers n=1,2,3,4,5\displaystyle n = 1, 2, 3, 4, 5.
Therefore, the missing third term must be 43\displaystyle 4^3:
43=644^3 = 64
Hence, **Option C** is the correct answer.
