Directions to Solve
Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.
18.
Which term of the series 5, 8, 11, 14,.....is 320?
Answer: Option
Explanation:
Clearly, 5 + 3 = 8, 8 + 3 = 11, 11 + 3 = 14, .....
So, the series is an A.P. in which a - 5 and d = 3.
Let 320 be the nth term of the series.
Then, 320 = 5 + (n - 1) x 3 or (n - 1) = 105 or n = 106.

Remember, the formula for finding nth term in an Arithmetic Progression(AP) is :
nth term = a+(n-1)d.
Where,
a is last term.
d is the difference.
nth term = a+(n-1)d.
Where,
a is last term.
d is the difference.
