Some puzzles look harmless at first glance. A few numbers, a neat pattern, one missing answer.
Then suddenly, your brain is doing laps like it has signed up for the Olympics. Ready to test yours?
Your challenge, should you choose to accept it
Maths has a funny way of dividing a room. Some people see a number puzzle and lean in with the quiet confidence of a chess grandmaster. Others suddenly remember they have laundry to fold, a plant to water, or an urgent need to stare into the fridge.
This little challenge belongs to the first category – deceptively simple, but just tricky enough to make you doubt yourself.
The task is clear: study the pattern, follow the logic, and work out the missing number. No fancy calculator required. Just patience, focus, and perhaps a strong cup of tea.
As the charity National Numeracy often reminds people, confidence with numbers matters in everyday life. And puzzles like this are a rather painless way to sharpen that skill without feeling as though you are back in a classroom.

Genius move or coffee break moment?
So, did the answer jump out at you? Or did the numbers sit there looking smug?
Do not worry either way. Even the sharpest minds can be caught out by a pattern that seems obvious only after someone explains it. That is the charm of a good brain teaser: it makes you work, then rewards you with that tiny ‘of course!’ moment.
A useful trick is to avoid overcomplicating things. Look for repetition, simple operations, or a hidden sequence. Sometimes the missing number is less about genius and more about refusing to panic when arithmetic starts wearing a little disguise.

The final thought
Whether you cracked it instantly or needed a second look, the point is not just the answer. It is the little workout your brain gets along the way.
So next time a puzzle appears on your screen, give it a proper go before scrolling past. Your inner calculator may be sharper than you think.
