# Tricky test: Are you smart enough to solve this math problem?

## 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.

In the picture below, we see several numbers in a row.

As quickly as you can, your task is to figure out the last number, right where the question mark is.

Here comes the math riddle.

Can you figure out the correct number?

It’s not easy, but if you concentrate, it should appear in your mind.

If you can’t, we’ll show you the answer below!

A

B

C

## Here is the solution

If you have thought about it carefully but haven’t found the correct answer, you can see it after the next picture.

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.

Did you get it right?
