Question 25

In the following question, select the missing number from the given series.
76, 23, 99, 122, 221, ?

Solution

The logic here is

76 + 23 = 99

23 + 99 = 122

99 + 122 = 221

Number in the series is equal to the sum of the previous two numbers in the series.

Similarly, the next number in the series = 122 + 221 = 343

$$\therefore\ $$The missing number in the series = 343

Hence, the correct answer is Option C
