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

Sequence is a list of numbers (or items) that exhibits a particular pattern.

Answer: For the given series 4+1=5, 5+2=12, 3+6=21, 8+11=96

Let's observe the pattern

Explanation:

According to the given series,

1+4= 1x4+1=5

2+5=2×5+2=12

3+6=3×6+3=21

Thus, we see that the result of the addition of two numbers x and y is: x + y = xy + x

Hence,

8+11=8×11+8=96

Therefore, the value of 8+11 is 96.
