Patterns that help
The last digits go 8, 6, 4, 2, 0 and then repeat.
18 is even, so every multiple of 18 is even too.
A quick check: It must be even AND its digits must add to a multiple of 9, because 18 = 2 × 9. 126 is even, and 1 + 2 + 6 = 9, so 126 is a multiple of 18.
Building the list from facts you know: Double the 9 times table: 18 × 7 is double 63, which is 126.
