One number is not like the others: 1331, 2197, 3375, 4096

Write each number as a cube

• 1331 = 113 -> cube of an odd number.

• 2197 = 133 -> cube of an odd number.

• 3375 = 153 -> cube of an odd number.

• 4096 = 163 -> cube of an even number.

Pattern

The first three numbers are cubes of odd numbers, while 4096 is the cube of an even number.

Final answer: 4096.
