**What is the last number?**

How much do you really remember from the math classes several years ago?

Therefore, the math challenge below has been popping around the internet a lot lately – precisely because not many people can solve it.

Here is the challenge.

In the picture below we can see four numbers. By looking at them, you should be able to calculate the next number, where the question mark is located.

Now look at the picture – and remember that you only have ten seconds to solve it!

Were you able to solve this math challenge? Big congratulations if you were, you really do remember the math from back in school!

If you weren’t, the answer is below the next picture.

**Time for the answer**

**The answer is 96.**

How did we get there?

If you look at the first two numbers, we see that the difference between them is 13: 32 + 13 = 45.

In the next number, we see that the difference between them is 15: 45 + 15 = 60.

So that would be 13 + 2 = the difference. You can see where we are going with this.

If we go one step further, the difference now is 17 between the numbers: 60 + 17 = 77. So 15 + 2 = the difference.

Then, using common sense, we can add another 2 for the next difference, which becomes 19.

Then the last parts looks like this: 77 + 19 = 96.

The answer, in conclusion, is 96.
