Three numbers from the following four numbers are somehow identical and one number is uneven. Select that uneven number.

Options

A. 254
B. 217
C. 126
D. 730

Answer

A

Explanation

`6^3 + 1= 216 + 1 = 217`
`5^3 + 1= 125 + 1 = 126`
`9^3 + 1= 729 + 1 = 730`
254 doesnt follow the above pattern.
Therefore, option (a) is different.
