Abigail from Histon and Impington Infants School sent a very clear solution to this problem:

I used some counters to represent the cherries. I did what Suzie did and worked out that if you started with 4 cherries, you would end up with 1 left after doing pair, pair, single. If you started with 8 cherries, you would end up with 2. If you started with 12, you would end up with 3, and if you started with 16, you would end up with 4.
I spotted that the end numbers went up by one each time, and the start numbers went up by four. Then I did a table:

Table of results for Cherries Come in Two's!
Start End
4 1
8 2
12 3
16 4
20 5
24 6
28 7
32 8
36 9
40 10
44 11
48 12
52 13
56 14

So there were 56 cherries in the bowl at the start.

Well reasoned, Abigail.
