Question : Directions: In the following question a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series.
3.5, 7, 10.5, 14, ?
Option 1: 15.5
Option 2: 16.5
Option 3: 18.5
Option 4: 17.5
Correct Answer: 17.5
Solution :
Given:
3.5, 7, 10.5, 14, ?
In the above-given series, add 3.5 to the previous term to get the next term –
3.5 + 3.5 = 7; 7 + 3.5 = 10.5; 10.5 + 3.5 = 14; 14 + 3.5 = 17.5
So, 17.5 is the missing term of the series. Hence, the fourth option is correct.
