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

The 25^(th) term of an arithmetic sequence is 140 and the 27^(th) term is 166 . What is its common difference? What is its 35^(th) term?

The sum of first 9 terms of an arithmetic sequence is 45 and the sum of first 18 terms is 171. What is its 5^(th) term?

The 5^(th) term of an arithmetic sequence is 38 and 8^(th) term is 62. What is the common difference in the sequence?

The common difference of the arithmetic sequence 15, 14, 13, 12,......is 14-15=-1. First term of the sequence is 15 and the 15^(th) term is 15 + 14 xx-1= 15-14=1 . Similarly the 4^(th) term is 12 and the 12^(th) term is 4. Its 16^(th) term is x_16 = 15 + 15xx-1= 15-15 = 0 . So the sum of the first 31 terms is also zero. That is if then n^(th) term of an arithmetic sequence with common difference -1 is m, then the m^(th) term is n and the (m + n)^(th) term is zero. 7^(th) term of an arithmetic sequence is 10 and the 10^(th) term is 7. What is the common difference?

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?
