Find the odd one out.

1. 4: 16: 256
2. 3: 9: 81
3. 5: 25: 125
4. 6: 36: 1296

Correct answer: 5: 25: 125

Solution

In A, B, and D, the second term is the square of the first and the third term is the square of the second: $4,16,256$; $3,9,81$; $6,36,1296$. In C, $5,25,125$ does not follow this pattern because 125 is not the square of 25. Hence, it is the odd one out.
