Question 1The general term of a sequence is given by an = -4n + 15. Is the sequence an A. P.? If so, find its 15th term and the common difference.

Question 2The nth term of an A. P. is 6n + 11. Find the common difference.

Question 3If the 8th term of an A. P. is 31 and the 15th term is 16 more than the 11th term, find the A. P.

Question 4Which term of the arithmetic progression 5, 15, 25, ----- will be 130 more than its 31st term?

Question 5Which term of the A. P. 3, 15, 27, 39…… will be 132 more than its 54th term?
Question 6Two A. P.’s has the same common difference. The difference between their 100th terms is 111 222 333. What is the difference between their Millionth terms?
Question 7The 10th and 18th terms of an A. P. are 41 and 73 respectively. Find 26th term.
Question 8If (m + 1)th term of an A. P. is twice the (n + 1)th term. Prove that the (3m + 1)th term is twice the (m + n + 1)th term.

Question 9If the nth term of the A. P. 9, 7, 5… is same as the nth term of the A. P. 15, 12, 9…. find n.
Question 10Find the second term and nth term of an A. P. whose 6th term is 12 and the 8th term is 22.

Question 12If an A. P. consists of n terms with first term a and nth term l show that the sum of the nth term from the beginning and the mth term from the end is (a + l).
Question 13If the ath term of an A. P. be 1/b and bth term be 1/a then show that its (ab)th term is 1.
Question 14If the pth term of an A. P. is q and the qth term is p. Prove that its nth term is (p + q – n)
Question 15If m times the mth term of an A. P. is equal to n times its nth term. Show that the (m + n)th term of the A. P. is zero.
