Question #1
What will come in place of the question mark (?) in the following number series? 4, 8, 12, 20, ?
A. 28
B. 36
C. 24
D. 32

Correct Answer: Option D


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.
