Consider arithmetic sequence 180,176,172,........ Find the 20th term of this sequence

Consider arithmetic sequence 180,176,172,........ Is 0 a term of this sequence? Justify?

Consider the arithmetic sequence 171,167,163,... i) Is '0' a term of this sequence? Why? ii) How many positive terms are in this sequence?

Consider arithmetic sequence 180,176,172,........ How many positive terms are there in this sequence?

Find the n^(th) term of the sequence 3,5,7,………

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

Find the n^th term of the sequence 5,2,-1,-4,-7,…

For an arithmetic sequence 22,26,30,..... Will 50 be a term of this sequence ? Why?

Consider the arithmetic sequence 13,23,33,... What is the first three digit term of this 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 algebraic form of an arithmetic sequence is 6n+5. Find the sum of first 20 terms of this sequence?
