# Maths Detectives – Pattern spotting

As mathematician we know the importance of pattern spotting. We have used our maths detective skills to investigate patterns in adding and subtracting 4 consecutive numbers (numbers that follow on from each other E.g. 1, 2, 3 and 4.)

What did we notice?

Molly and Seb noticed that when they added the two middle numbers in +++ and then double the result they got the answer. For example: 2+ 3+ 4+ 5 = 14

Inari noticed that with ++- if you double the first number in the calculation this gives the answer to the whole calculation. For example: 1+2+3-4 = 2

Samuel noticed that everytime he did +– he got an answer of -4.

Alex noticed –+ the answer is 0.

Andria said that all the consecutive numbers answers should be even. If they are odd they are wrong.

Can you be a mathematics detective too? Why not try investigating adding and subtracting consecutive numbers at home and looking for patterns. You never know, you might find a pattern that someone has never seen before.

I really liked doing this maths investigation and at first I thought it was easy but it turned out to be challenging. Finlay

Well done Scott for answering those maths problems.Sam.L

I liked this lesson because it was challenging and I like a challenge. Millie Poole.
