If first term is `-1` and common difference is `(-1)/(2)` find the `n^(th)` term.

The first term of an A.P. is 5 and its common difference is -3 . Find the 11th term of an A.P.

The first term of an AP is p and its common difference is q. Find its 10th term.

If the sum of the first 12 terms of an A.P.is 468 and its common difference is 6, find the 10th term.

A sequence is called an A.P if the difference of a term and the previous term is always same i.e if a_(n+1)- a_(n)= constant ( common difference ) for all n in N For an A.P whose first term is 'a ' and common difference is d has n^(th) term as t_n=a+(n-1)d Sum of n terms of an A.P. whose first term is a, last term is l and common difference is d is S_(n) = n/2 (2a +(n-1)d)=n/2 (a+a+(n-1)d)= n/2 (a+l) a_1,a_2,a_3,....a_8 is an A.P. with common difference d. Then a_(8-2k)-a_k(1 leklt4 k in N) is equal to

A sequence is called an A.P if the difference of a term and the previous term is always same i.e if a_(n+1)- a_(n)= constant ( common difference ) for all n in N For an A.P whose first term is 'a ' and common difference is d has n^(th) term as t_n=a+(n-1)d Sum of n terms of an A.P. whose first term is a, last term is l and common difference is d is S_(n) = n/2 (2a +(n-1)d)=n/2 (a+a+(n-1)d)= n/2 (a+l) If sum of n terms S_n for a sequence is given by S_n=An^2+Bn+C , then sequence is an A.P. whose common difference is
