11*10 = 110+10 = 120.
10*9 = 90 +9 = 99.
9*8 = 72 +8 = 80.
8*7 = 56 +7 = 63.
7*6 = 42 +6 = 48.
6*5 = 30 +5 = 35.
10*9 = 90 +9 = 99.
9*8 = 72 +8 = 80.
8*7 = 56 +7 = 63.
7*6 = 42 +6 = 48.
6*5 = 30 +5 = 35.

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.

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

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.

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.
