What is the next number in the series: 5, 10, 15, 20?

  1. 25

  2. 30

  3. 35

  4. 40

The correct answer is: 25

The series presented consists of numbers that are increasing in a consistent manner. Each number is separated by a difference of 5. Starting with 5, when you add 5, you get 10. Adding 5 again gives you 15, and another addition of 5 results in 20. To find the next number in the series, you continue this pattern by adding 5 to 20. Doing so leads you to 25. This consistent increment of 5 establishes the pattern, confirming that 25 is indeed the next number in the sequence.
