1+4=5,2+5=12,3+6=21,8+11=96

because 8+11=(8+11*8)=8+88=96

because 8+11=(8+11*8)=8+88=96

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

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
