# This looks like an ordinary sequence of numbers – but can you spot what’s wrong?

The human brain is incredible, the things it can remember and learn are what separates us from animals. But when faced with something designed to fool it – it’s quick to play pranks on us – without even noticing.

When we come across a riddle or visual illusion, we often see or perceive only part of the truth. However, that is the charm of these challenges.

In recent times, perhaps because of this, it has become a bit of an online trend to challenge friends and family with a brainteaser to find out who has the sharpest brain!

Not many people pass this next test on the first try. But if you give yourself some time, you will probably end up solving it. However, if we add a bit of a time limit, things will get more interesting. Can you solve it in under 20 seconds?

Below, you can see a sequence of numbers between 1 and 53, but two numbers are missing. Your challenge is to find them!
