The given number is which term of the arithmetic sequence
Problem 1 :
Which term of the AP : 3, 8, 13, 18, …is 78 ?
Problem 2 :
Which term of the AP : 3,15,27, 39, … will be 120 more than its 21st term?
Problem 3 :
The 17th term of an A.P. exceeds its 10th term by 7, Find the common difference.
Problem 4 :
Find whether - 150 is a term of the AP 17, 12, 7, 2, … ?
Problem 5 :
170 is the nth term of -4, 2, 8, .............
Problem 6 :
97 is the nth term of -3, 1, 5, ......
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.
6) n = 26
