Find the odd one out: 8, 27, 64, 100, 125
Explanation
Explanation
Step 1: Look for the common property. 8 = 2³, 27 = 3³, 64 = 4³ and 125 = 5³.
Step 2: These four numbers are all perfect cubes.
Step 3: 100 is not a perfect cube because 4³ = 64 and 5³ = 125, and 100 lies between them. It is a perfect square (10²) instead.
Answer: 100.
PRO TIP
Re-check your working by substituting the answer back into the original question.
