The pattern is simple,
1+4 = 5
The next number is actually 7 because 2+5 =7
But it is added to the previous result ,ie , 7+5 = 12
so , the result of 2+5 = 12
And it goes on like that.
So 3+6 is actually 9 but it is added to 12 to get 21

So the pattern would be ,
1+4 = 5
2+5 = 12
3+6 = 21
4+7 = 32
5+8 = 45
6+9 = 60
7+10 = 77
And 8+11 = 96

Therefore, 8+11 = 19 actually but we have to add 77 to it to get the right answer of this pattern which is 96

So , 8+11 = 96
