Question
Select the odd group of numbers.(NOTE: Operations
should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 - operation on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)Solution
11: 126 → 11² + 5 = 121 + 5 = 126 15: 230→ 15² + 5 = 225 + 5 = 230 8: 69 → 8² + 5 = 64 + 5 = 69 17: 296 → 17² + 5 = 289 + 5 = 294.
