1. Find each unknown: a) □ − 17 = 48 b) 100 − □ = 63
2. Describe the rule and give the next two terms: 1, 2, 4, 8, 16, , . Rule:
3. This pattern goes 4, 7, 10, 13… Will 30 ever appear? Explain why or why not.
4. Write three different number sentences that all equal 24 (use +, −, × ).
5. Pip's star pattern adds 2, then 4, then 6, then 8… Starting at 1, write the first six numbers.
