When skip counting, we increase or decrease the number by a certain amount with each step. You can find the amount to step by looking at the difference between each pair of numbers in the sequence.
For example, if we have the numbers 2, 4, 6, 8, the difference between each pair of numbers (i.e. 4-2, 6-4, and 8-6) is 2. So, we are skip counting by 2.
