Correct Answer: 121


Solution : Given:
100, 105, 92, 113, 84, ?

In the above-given series, add and subtract alternately, the natural numbers with the difference of 8 to the numbers.
100 + 5 = 105;
105 – (5 + 8) = 105 – 13 = 92;
92 + (13 + 8) = 92 + 21 = 113;
113 – (21 + 8) = 113 – 29 = 84;
84 + (29 + 8) = 84 + 37 = 121

So, 121 is the missing number. Hence, the third option is correct.
