Add all the numbers and then divide it with 6. Because there are total 6 nos given, as the answer will come.
E.g: 7+10+8+11+9+12=57.
57/6 = 9.5.
Round figure is 10.
E.g: 7+10+8+11+9+12=57.
57/6 = 9.5.

The first pattern 3 is added & second pattern 2 is subtracted.
7 + 3 = 10,
10 - 2 = 8,
8 + 3 = 11,
11 - 2 = 9,
9 + 3 = 12,
12 - 2 = 10.
The correct answer is 10.
7 + 3 = 10,
10 - 2 = 8,
8 + 3 = 11,
11 - 2 = 9,
9 + 3 = 12,
12 - 2 = 10.
The correct answer is 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.

It's a very simple.
7, 10, 8, 11, 9, 12, ...
Divide in to two parts.
1st -> 7 8 9.
2nd -> 10 11 12.
So the next number would be 10.
7, 10, 8, 11, 9, 12, ...

Look at this series: 7, 10, 8, 11, 9, 12, .
Ans -7+3 = 10,
8+3 = 11,
9+3 = 12,
10 -- Ans (7+1,8+1, (9+1) - Ans.
Ans -7+3 = 10,
8+3 = 11,
9+3 = 12,
10 -- Ans (7+1,8+1, (9+1) - Ans.

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.
