Arithmetic Prog...

In an arithmetic progression, if $${ S }_{ n }=n(5+3n)\quad and\quad { t }_{ n }=32$$, then the value of n is
[Note: $${ S }_{ n }$$ and $${ t }_{ n }$$ denote the sum of first n terms and $${ n }^{ th }$$ term of arithmetic progression respectively.]

If the sum of the three consecutive terms of A.P is $$48$$ and product of the first the last is $$252$$, and d=........

The sum of five consecutive odd numbers is 295. The smallest number is

Let a, b, c be three distinct positive numbers which are in G.P, if $${ log }_{ c }a,{ log }_{ b }c,{ log }_{ a }b$$ are in A.P., then the common difference of the A.P is 

The number of common terms in two AP's 2, 5, 8, 11,..., 179 and 3, 5, 7, 9, .. 101 are 

The sum of n terms of an AP is $$(3n^2 + 5n).$$ Which of its terms is 164?

In an AP, the correct relation is

In an A.P $$a_{n + 5} = 50$$ and $$a_{n + 1} = 38$$ then common difference

How many terms of the AP 6, 12, 18, 24,.... must be take to make the sum 816?

How many terms of the $$ AP -5, \frac{-9}{2}, -4, $$ .... will give the sum $$0$$?
