What should come in place of the question mark ‘?’ in the following number series?1680, 210, 30, 5, ?, 0.25
Question
Solution 1
The given series is a decreasing series. If we observe closely, each number is divided by 8 to get the next number.
1680 ÷ 8 = 210, 210 ÷ 7 = 30, 30 ÷ 6 = 5, 5 ÷ ? = 0.25
To find the missing number, we need to divide 5 by 0.25.
5 ÷ 0.25 = 20
So, the missing number is 20. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem. Knowee AI Study
