▼

We are given the sequence:
4, 7, 12, 15, 20, ?

Let’s analyze the pattern by looking at the differences between consecutive terms:

- 7 – 4 = +3
- 12 – 7 = +5
- 15 – 12 = +3
- 20 – 15 = +5

So the pattern of differences is: +3, +5, +3, +5

This suggests an alternating pattern of adding 3 and then 5.

Following this logic, the next step after +5 should be +3 again.

So:
20 + 3 = 23

✔ Therefore, the next number in the sequence is 23.

Looking at the options:

- A: 26
- B: 21
- C: 22
- D: 23 ← Correct
- E: 24
- F: 25

✔ Final Answer: D. 23
