How to think it through (Find the jump): Write the jump between each pair of neighbours (+3, +3, +3 … or × 2, × 2 …). If the jumps are not equal, look at the jumps themselves: do they grow by 1, take turns, or are the numbers squares (1, 4, 9, 16 …)? Use the same rule once more to get the next number.
