5^(th) term of an arithmetic sequence is 17 and the 17^(th) term is 5. Which term of the sequence is zero?

The sum of first n terms of an arithmetic sequence is n^2+2n What is the sum of first 20 terms of this sequence?

The 8^(th) term of an arithmetic sequence is 12 and its 12^(th) term is 8.What is the algebraic expression for this sequence?

The 20th term of an arithmetic sequence is 64 and its 21^(st) term is 70. .Can the difference between two terms 46? Why?

The 8^(th) term of an arithmetic sequence is 12 and its 12^(th) term is 8 . What is the. algebraic expression for this sequence?

The 5^(th) term of an arithmetic sequence is 38 and the 9^(th) term is 66. What is its 25^(th) term?

The 5^(th) term of an arithmetic sequence is 38 and the 9^(th) term is 66. What is its 25^(th) term?

Read the following Passage. Understand the Mathematical concept in it and answer the questions that follow. Each question carries 1 score. The common difference of the arithmetic sequence 15,14,13,12,...... is 14-15=-1 . First terms of the sequence is 15 and the 15th term is 15+14x-1=15-14=1 . Similarly the 4th term is 12 and the 12^(th) term is 4. Its 16th term is, x_(16)=15+15x-1=15-15=0 . So the sum of the first 31 terms is also zero. that is if the n^(th) is m, then the mth term is n and the (m+n)^(th) term is zero. Seventh term of an arithmetic sequence is 10 and the 10^(th) term is 7. What is the common difference?

Find the 20^(th) term of an arithmetic sequence if its 6^(th) term is 14 and 14^(th) term is 6.
