What is the next number in the series: 10, 20, 30,…?

• A. 35
• B. 40
• C. 50
• D. 60

Answer: (B)

The series presented is a sequence where each consecutive number increases by the same amount, which in this case is 10. Starting from 10, the next number is found by adding 10 to the previous number. Thus, adding 10 to 10 gives us 20, and adding another 10 to 20 results in 30. Continuing this pattern, to find the next number after 30, we again add 10. Therefore, 30 + 10 equals 40. This consistent addition of 10 is what defines the progression of this series. The correct answer reflects the consistent rule of increasing each number by 10, confirming that 40 is the next logical step in the sequence.
