A sequence is a list of numbers that follow a rule. You might need to find the next number or the missing one in the middle.

Look at the difference between consecutive numbers (e.g. +3 each time) or another pattern, then apply the same rule to find the answer.

Examples
2, 4, 6, 8, ? → 10
5, 10, 15, ? → 20
