Answer 2

Method - 1:

(i)

= > 1 + 7 + 1^2

= > 1 + 7 + 9

(ii)

= > 2 + 14 + 2^2

= > 2 + 14 + 4

= > 20

(iii)

= > 3 + 105 + 3^2

= > 3 + 105 + 9

= > 3 + 105 + 117.

So, the answer is 20.

But, we should not solve in this way as it not a series question!

------------------------------------------------------------------------------------------------------

Method - 2:

(i)

2 * 1 + 1

= 3

(ii)

14 * 7 + 7

105.

(iii)

x * 9 + 9 = 117

= > 9x = 108

= > x = 12.

Therefore, the number is 12 - Option (D)

Hope this helps!
