Part B: Matching
Match each pattern to the correct missing number.
1. Draw a line to match each pattern to its missing number.
10, 20, 30, ___, 50
→ 40
115
95, 100, 105, ___, 115
→ 110
56
50, 52, 54, ___, 58
→ 56
40
110, ___, 120
→ 115
110
Counting by 10s: add 10 to 30 to get 40. Counting by 5s: add 5 to 105 to get 110, and add 5 to 110 to get 115. Counting by 2s: add 2 to 54 to get 56.
