Age 7 to 11

Challenge Level

Susie had a large bowl of cherries.

They were all in pairs.

Susie took out a pair, she ate one cherry and put the other one
back. She took out another pair and did the same again.

Then she helped herself to one of the single cherries in the
bowl.

Susie continued helping herself to the cherries in this way (pair, pair, single - pair, pair, single - ...)

After she had done this lots of times, there were just $14$ single cherries left.

How many cherries had there been in the bowl to start with?
