Solution

Problem 2 :

Which term of the AP : 3,15,27, 39, … will be 120 more than its 21st term?

Solution

Problem 3 :

The 17th term of an A.P. exceeds its 10th term by 7, Find the common difference.

Solution

Problem 4 :

Find whether - 150 is a term of the AP 17, 12, 7, 2, … ?

Solution

Problem 5 :

170 is the nth term of -4, 2, 8, .............

Solution

Problem 6 :

97 is the nth term of -3, 1, 5, ......

Solution

1)  16th term of the AP is 78.

2)  Therefore, the 31st term of the given AP is more than the 21st term.

3)  So, the common difference is 1.

4)  So, -150 is not a term of the given AP.

5)  So, 30th term of the sequence is 170.
