Multiple choice general knowledge math & puzzles Pick the odd one 1,4,9,256,3125,... 1 4 9 256 Reveal answer Fill a bubble to check yourself C Correct answer Explanation The sequence is n^n: 1^1=1, 2^2=4, 3^3=27 (but the list says 9), 4^4=256, 5^5=3125. 9 is the odd one out because it is 3^2, whereas the pattern requires 3^3=27. Thus, 9 does not fit the n^n rule.
