D Correct answer
Explanation

The pattern follows n raised to the power of n squared: 1^(1²) = 1^1 = 1, 2^(2²) = 2^4 = 16? No. Try powers of powers: 1^2=1, 2^3=8? No. Actually: 1^1=1, 2^3=8, 3^4=81, so blank should be 4^5=1024, then 5^6=15625. Pattern: n raised to (n+1) power, starting with n=1.

AI explanation

The rule is n raised to the power (n+1): 1^2=1, 2^3=8, 3^4=81, 4^5=1024, 5^6=15625. So the missing term follows 4^5, giving 1024. 512 (2^9) and 256 (2^8) don't fit the increasing-exponent pattern of the other terms.
