Which number comes next in the series shown below: 10, 34, 50, 68, 88, ?
- 98
- 94
- 108
- 110
Explanation
Given sequence:
10, 34, 50, 68, 88, ?
Now look at the differences between the numbers:
- 34 − 10 = 24
- 50 − 34 = 16
- 68 − 50 = 18
- 88 − 68 = 20
The differences are: 24, 16, 18, 20
Now see the pattern in differences:
24, 16, 18, 20 → decreasing, then increasing by 2
So if this trend continues, the next difference should be:
22
88 + 22 = 110
