For an A.P. if the first term is 8 and the common difference is 8, then `S_(n)`=

If for an A.P. the first term is 11 and the common difference is (–2), then find first three terms of A.P.

If for an A.P. the first term is 11 and the common difference is (–2), then find first three terms of A.P.

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 is S_(n) = n/2 (2a +(n-1)d)=n/2 (a+a+(n-1)d)= n/2 (a+l) A sequence whose n^(th) term is given by t_(n) = An + N , where A,B are constants , is an A.P with common difference

In an A.P., if the first term is 22, the common difference is -4 and the sum to n terms is 64, find n .

In an A.P., if the first term is 22, the common difference is -4 and the sum to n terms is 64, find n .

The AP with first term is 8 and common difference 2 1/2 is ……………
