What will come in place of the question mark (?) in the following number series? 4, 8, 16, 32, ? MCQ with Answer and Explanation

Explanation:
The differences are: 9, 13, 17. These are increasing by 4. The next difference is 21. Therefore, 46+21=67.

Explanation:
The pattern alternates: +4, ×2? No, 4+4=8, 8+4=12, 12+8=20. Actually, it's adding consecutive even numbers: +4, +4, +8. But more precisely: 4+4=8, 8+4=12, 12+8=20, 20+12=32? Let's re-evaluate: The differences are 4, 4, 8, 12. Not a clear pattern. A better pattern: each term is the sum of the previous two terms? 4+8=12, 8+12=20, 12+20=32. Yes, this is a Fibonacci-like series. The next term is 12+20=32.

Explanation:
The differences are: 7, 8, 9. The next difference is 10. Therefore, 29+10=39.
