The number in the place of '?' should be1. 42 2. 58 3. 594. 68

Answer»

Correct option: (4) 68

Explanation:

Sum of squares of all numbers - sum of numbers

[(3)2 + (2)2 + (2)2 + (4)2] - [3 + 2 + 2 + 4] = 22

[(4)2 + (3)2 + (2)2 + (5)2] - [4 + 3 + 2 + 5] = 40

[(5)2 + (4)2 + (3)2 + (6)2] - [5 + 4 + 3 + 6] = 68
