Question : Directions: Which number will replace the question mark (?) in the following number series? 8,13, 23, 43,?
Option 1: 83
Option 2: 86
Option 3: 81
Option 4: 84
Correct Answer: 83
Solution : Given: 8,13, 23, 43,?
Add twice the difference of the previous number to get the missing number – 8 + 5 = 13, 13 + 10 = 23, 23 + 20 = 43, 43 + 40 = 83
So, 83 is the required missing number in the series. Hence, the first option is correct.
