Question

15-16) 4, 6, 9, 11, 14, 16, _____, 21, ______

Pattern:

Missing Terms:





17-18) 3, 6, 7, 14, 15, _____, ______



Pattern:

Missing Terms:

Answer 1

first pattern: +2, +3 (repeated)

first missing terms: 19, 24

second pattern: *2, +1

second missing terms: 30, 31

Explanation:

first pattern:

1. subtract the second term with the first, (6-4=2) then then third with the second (9-6=3).

2. repeat until to prove the pattern, +2, +3

3. apply pattern to missing term, (16+2=19) and (21+3=24)

second pattern:

1. since subtracting the terms does not give us a pattern, try dividing when possible, (6/3=2) and (14/7=2). then subtract the other terms (7-6=1) and (15-14=1)

2. find pattern from calculation, *2, +1.

3. apply pattern to missing terms, (15*2=30) and (30+1=31).

hope this helped! ♡
