Rule: Number sequences

Find how each number becomes the next: how much is added (taken away), or how many times bigger it gets.

Test the rule on every pair of neighbours, not just the first.

Example: 2, 6, 18, 54: each number is 3 times bigger → the next is 162

Watch out: The differences need not be equal: 3, 8, 18, 38 is “times 2, plus 2”, the next is 78.
