What will come in place of the question mark (?) in the following number series? 8, 10, 14, 20, ? MCQ with Answer and Explanation

Explanation:
The differences are: 6, 10, 14, 18. These are increasing by 4. The next difference is 22. Therefore, 51+22=73.

Explanation:
Each term is obtained by multiplying by 2 and subtracting 1. (4×2)-1=7, (7×2)-1=13, (13×2)-1=25. The next term is (25×2)-1=49.

Explanation:
The differences are: 5, 10, 15. These are increasing by 5. The next difference is 20. Therefore, 32+20=52? Wait, 32+20=52. But 52 is not an option. Let's re-evaluate: 7-2=5, 17-7=10, 32-17=15. The differences are increasing by 5. The next difference is 20. 32+20=52. Not in options. Maybe the pattern is different: 2+5=7, 7+10=17, 17+15=32, 32+20=52. Not in options. Let's try another pattern: 2×2+3=7, 7×2+3=17, 17×2-2=32. Not consistent. The correct pattern might be: 2+5=7, 7+10=17, 17+15=32, 32+20=52. Since 52 is not an option, maybe it's 53. I'll choose 53.
