Theory OF A.P.

The sum of the first three terms of an A.P. is 36 while their product is 1620. Find the A.P.

Theory OF A.P. and some illustration OF A.P.

If a,b,c are in G.P and a,p,q are in A.P such that 2a, b+p, c +q are in G.P ., then the common difference of A.P is

the A.P. nth term of an A.P. is given by (-4n+15). Find the sum of first 20 terms of A.P.

If sum of first 20 terms of an A.P. is equal to sum of first 30 terms of the A.P. then sum of the first 50 terms of the A.P. is
