10 × 6 + 1 = 61

11 × 7 + 1 = 78

12 × 8 + 1 = 97

13 × 9 + 1 = 118

14 × 10 + 1 = 141 (142)

61 - 46 = 15    

78 - 61 = 17

97 - 78 = 19

118 - 97 = 21

142 - 118 = 24

Difference between 15 and 17 = 2

Difference between 17 and 19 = 2

Difference between 19 and 21 = 2

Difference between 21 and 24 = 3

So wrong answer is 142
