Question : Directions: In the following question observe the series and figure out the pattern used to form it. What will be the 3rd term of the series?
1, 5, ?, 22, 35
Option 1: 11
Option 2: 14
Option 3: 10
Option 4: 12
Correct Answer: 12
Solution :
Given:
1, 5, ?, 22, 35
The difference between each consecutive term is increasing by 3 –
1 + 4 = 5
5 + (4 + 3) = 5 + 7 = 12
12 + (7 + 3) = 12 + 10 = 22
22 + (10 + 3) = 22 + 13 = 35
So, 12 is the missing term. Hence, the fourth option is correct.
