Have a go at this **SEQUENCES **question by analysing the numbers in the list. When you’ve worked out the relationship between the numbers, have a go at answering the following question:

**What is the 7th number that should appear in this sequence, and why? Quite a tough ask today, so a clue would be to think square numbers and prime numbers!!**

**2 5 11 17 29 37 ?**

Got an answer? Leave a comment below or e-mail me at **paul@7puzzle.com**.

The answer is 53, the numbers are the first prime after successive square numbers, quite a tough one if you hadn’t given the clues

Superb, well done Martin.
