A pattern of flower counts goes 2, 5, 11, 23. Using the rule “double the previous number, then add one,” what comes next?
A little nudge?
Apply both parts of the rule to 23.
Ready for the answer?
47
23 × 2 = 46, and 46 + 1 = 47. Stating the rule matters: a short number sequence can otherwise have many possible continuations.
