Skip counting means, adding or reducing multiple times by the same number. The image shows a number of examples.
It is possible to calculate how big the skip is. For example if you have a row of numbers: 3 6 9 12 you can take 2 numbers that are next to each: 6 and 9 then you take the biggest of the two and substract it with the smaller one so 9-6=3 and now you know that the skip is 3
2 4 6 8 10 6-4=2
7 14 21 28 28-21=7
300 400 500 600 500-400=100
