What comes next in the series: 63, 48, 35, 15, ___?
- 7
- 2
- 5
- 0
Explanation
63, 48, 35, 15, ?
Now, find the differences between consecutive terms:
- 63 → 48 → −15
- 48 → 35 → −13
- 35 → 15 → −20
Wait, something's off. Let's double-check with consistent logic.
Try this:
63 - 15 = 48
48 - 13 = 35
35 - 20 = 15
Now we got:
-15, -13, -20 → Pattern doesn't seem linear.
Try checking the alternating pattern:
- 63 → 48 (−15)
- 48 → 35 (−13)
- 35 → 15 (−20)
- 15 → ? (maybe −13 again?)
If the pattern alternates between −15, −13, −20, −13, then:
15 − 13 = 2
