Can you find the next number in this sequence?
An seemingly simple puzzle… but one that has baffled thousands of people! Â
Watch this series carefully:
10 → 15 → 25 → 40 → ?
The logic lies in the differences between the numbers:
- 10 + 5 = 15
- 15 + 10 = 25
- 25 + 15 = 40
- We notice that we are adding 5 more each time than before:
- +5
- +10
- +15
The next step is therefore:
40 + 20 = 60
