Here there is another method.
11*10+10
10*9+9
9*8+8
8*7+7
7*6+6
If we follow like this answer will be;
6*5+5 which is 35.
11*10+10
10*9+9
9*8+8
8*7+7
7*6+6
If we follow like this answer will be;
6*5+5 which is 35.

11*11-1 = 120.
10*10-1 = 99.
9*9-1 = 80.
8*8-1 = 63.
7*7-1 = 48.
6*6-1 = 35.
10*10-1 = 99.
9*9-1 = 80.
8*8-1 = 63.
7*7-1 = 48.
6*6-1 = 35.

Hi all,
I got correct answer like this,
120 - 80 = 40
99 - 63 = 36
80 - 48 = 32
63 - x = 28
so x is 35. All differences vary with a value of 4 in decreasing order. I know its too complicated. But reasoning
never results with one exact answer. We can have arrive at different possible answer(s).

-21, -19, -17, -15, -13.
So here 48-13=35.
So here 48-13=35.

The given series is 120,99,80,63,48.... the difference between the series is ie 120-99=21... like this 99-80=19;
17, and 15... the main diff b/w the answer is 2 for all so at the end 63-48 we got 15 so 15-2=13 there fore 48-13=35.
So simple.

99 to 21:120.
80 to 19:99.
63 to 17:80.
48 to 15:63.
So the 35 plus 13: 48.
80 to 19:99.
63 to 17:80.
48 to 15:63.
So the 35 plus 13: 48.
