Question : Directions: In the following question observe the series and figure out the pattern used to form it. What will be the next term of the series? 1, 3, 6, 10, 15, ?
Option 1: 32
Option 2: 21
Option 3: 42
Option 4: 34
Correct Answer: 21
Solution : Given: 1, 3, 6, 10, 15, ?
Add consecutive natural numbers from 2 onwards to find the next term of the series – 1 + 2 = 3; 3 + 3 = 6; 6 + 4 = 10; 10 + 5 = 15; 15 + 6 = 21
So, the next term of the series is 21. Hence, the second option is correct.
