Perri-Jane from Halstead Preparatory School in England explored the first Number Jumper sequence:

This number jumper only highlights even numbers 2,4,6,8,10,12,14... and it goes on until 98. This number sequence shows a pattern of 10 blue rows. When I looked at the coding, you can see it highlights, then adds 2, so for example; you have the number 2, highlight it, +2. Now it said repeat, meaning it will keep repeating from 1-99 (as it said at the start of the algorithm)

Well done for exploring the code in the left-hand panel. How is this different for the other Number Jumper sequences?

Dhruv from St. Anne's RC Primary School in the UK sent in this solution:

Well done for working out what happens in each Number Jumper sequence. How could you describe each sequence of numbers? Are they similar to any times tables?
