Can You Solve This ?

There are two answers to this viral puzzle. Can you figure out both?
A puzzle going viral on the Internet has everyone confused. The puzzle, which asks you to find a pattern between four equations, has two answers – and has led to numerous heated debates online. In fact, if the Daily Mail is to be believed, only one in a 1,000 people can figure out the second answer. Go ahead and see if you can solve it:

The two answers to the puzzle are 40 and 96.

For the first solution, you begin with 1 + 4 to get 5.

Then, you add 2 + 5 to the first answer of 5 to reach 12.

Similarly, adding 3 + 6 to 12 gives 21.

In the end, 8 + 11 + 21 = 40.

The quick answer, therefore, is 40, arrived at by simply adding each equation with the sum from the previous equation.

The second answer is also explained below. It is little more complicated.

Following that rule, other equations will be solved like this:

1 + (1 x 4) = 5

2 + (2 x 5) = 12

3 + (3 x 6) = 21

8 + (8 x 11) = 96

This puzzle has also annoyed people who discuss different answers with each other. However, many have pointed out that both the answers are correct since it is not a math puzzle but a logic puzzle.
