✓ Correct Answer: Option B Verified Solution

📘 Step-by-Step Solution & Detailed Explanation:

The sequence is 20, 32, 45, 59, 74, ...

Differences between consecutive terms:

32 - 20 = 12
45 - 32 = 13
59 - 45 = 14
74 - 59 = 15

The differences increase by 1 each time, so the next difference is 15 + 1 = 16.

The next term is 74 + 16 = 90.
