Its simple 3 add in first-time subt. 2 in second time.
7 + 3 = 10,
10 - 2 = 8,
8 + 3 = 11,
11 - 2 = 9,
Then,
12 - 2 = 10.
7 + 3 = 10,
10 - 2 = 8,
8 + 3 = 11,
11 - 2 = 9,
Then,
12 - 2 = 10.

First find out the difference of these nos
7-10=3.
10-8=2.
8-11=3.
11-9=2.
9-12=3.
Consider no 3 as no 2 as now.
7+3=10.
10-2=8.
8+3=11.
11-2=9.
9+3=12.
12-2=10.
7-10=3.
10-8=2.
8-11=3.
11-9=2.
9-12=3.
Consider no 3 as no 2 as now.
7+3=10.
10-2=8.
8+3=11.
11-2=9.
9+3=12.
12-2=10.

Answer is 10.
7+3 = 10-2 = 8+3 = 11-2 = 9+3 = 12-2 = 10.
7+3 = 10-2 = 8+3 = 11-2 = 9+3 = 12-2 = 10.
