There any be another logic for this question which,
Which,
(11)^2 - 1 = 120
(10)^2 - 1=99
(9)^2 - 1=80
(8)^2 - 1=63
(7)^2 - 1=48.
So with this conclusions;
(6)^2 - 1 = 35.
Which,
(11)^2 - 1 = 120

12 * 10 = 120
11 * 9 = 99
10 * 8 = 80
9 * 7 = 63
8 * 6 = 48
7 * 5 = 35.
11 * 9 = 99
10 * 8 = 80
9 * 7 = 63
8 * 6 = 48
7 * 5 = 35.

120-199=21
[21-19=2]
99-80=19
[19-17=2]
80-63=17
[17-15=2]
63-48=15
[15-13=2]
So subtract 48-13=35.
Finally, the difference between the series is 2.
[21-19=2]
99-80=19
[19-17=2]
80-63=17
[17-15=2]
63-48=15
[15-13=2]
So subtract 48-13=35.
Finally, the difference between the series is 2.

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.

There is another way:
11 * 11 - 1 = 120
10 * 10 - 1 = 99
9 * 9 - 1 = 80
8 * 8 - 1 = 63
7 * 7 - 1 = 48.
So, with this conclusion:
6*6 - 1 = 35.
11 * 11 - 1 = 120
10 * 10 - 1 = 99
9 * 9 - 1 = 80
8 * 8 - 1 = 63
7 * 7 - 1 = 48.
So, with this conclusion:
6*6 - 1 = 35.

There is another method....
10*12=120
9*11=99
8*10=80
7*9=63
6*8=48
now look at the series 1st multiples r 10,9,8,7,6,
So next is 5
look at 2nd multiples 12,11,10,9,8, so nxt comes 7
thr4 5*7=35
10*12=120
9*11=99
8*10=80
7*9=63
6*8=48
now look at the series 1st multiples r 10,9,8,7,6,
So next is 5
look at 2nd multiples 12,11,10,9,8, so nxt comes 7
thr4 5*7=35

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.
