Can you solve this really tricky numbers riddle in 60 seconds?

Alan Loughnane

We bet you can’t…

Maths is easy for some people, they like it, they get good grades and never struggle with their simple times tables.

But for others, it’s not quite as easy.

The riddle was created by Adam Spencer, comedian, mathematician, and author of The Number Games.

To figure it out, you have to figure out the sequence and fill in the last five numbers.

Here it is:

8, 18, 11, 15, 5, 4, 14, 9, 19, 1, 7, 17, 6, 16, ?, ?, ?, ?, ?

The answer is written below or you can just click and flip the picture to view the answer.

All that’s required to solve the puzzle is the ability to spell, being good at maths has diddly squat to do with it.

Spencer ordered the numbers in alphabetical order as they’re spelled. So, the missing last five numbers would be 10, 13, 3, 12, and 2 in that order.
