Which one number will complete the series : 8,13,10,15, 12, 17, 14.
- 20

- 22
Explanation
Series: 8, 13, 10, 15, 12, 17, 14, ?
Let’s break it into two alternating patterns:
- 1st, 3rd, 5th, 7th terms: 8, 10, 12, 14 → increasing by 2
- 2nd, 4th, 6th terms: 13, 15, 17 → increasing by 2
So next (8th) number continues the second pattern:
17 + 2 = 19
