Answer:
48, 28 respectively
Step-by-step explanation:
You would find the pattern for both.
1) 42, 43, 45, ?, 52
the pattern is +1, +2, +3, +4
42 + 1 = 43 +2 = 45 + 3 = 48 + 4 = 52
42, 43, 45, 48, 52
2) 23, ?, 33, 38, 43
the pattern is to add 5
23 + 5 = 28 + 5 = 33 + 5 = 38 + 5 = 43
23, 28, 33, 38, 43
