16^(th) term of an arithmetic sequence is 84 added to the 4^(th) term? If the 24^(th) term is 169 then What is the first term.

16^(th) term of an arithmetic sequence is 84 added to the 4^(th) term? If the 24^(th) term is 170 then Find the sum of first 24 terms.

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?

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

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 ratio between the 4^(th) term and 8^(th) term of an arithmetic sequence is 5: 11 . " "10^(th) term of this sequence is 56 i) What is the common difference of this sequence? ii) Find the 16^(th) term. iii) Find the sum of first 25 terms.

For the arithmetic sequence 6,12,18. Find the 10^(th) term?

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

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?
