In an AP,given a=5,d=3,a_(n)=50. Find n and S_(n)

In an AP: given a=5,d=3,a_(n)=50, find n and S_(n)

In an A.P: given a = 5 , d = 3, a_(n) = 50 , find n and S_(n)

In an A. P. : given a = 5, d = 3, a _(n) = 50, find n and S _(n).

In an A.P: given a = 2 , d = 8 , S_(n)= 90 , find n and a_(n) .

In an A.P. : (i) given a=5, d=3, a_(n)=50 , find n and S_(n) . (ii) given a=2, d=8, S_(n)=90 , find n and a_(n) . (iii) given a=3, n=8, S_(n)=192 , find d. (iv) given l=28, S=144, n=9 , find a.

In an A.P: given a_(n) = 4 , d = 2 , S_(n) = -14 , find n and a .

In an A.P: given a = 8 , a_(n)= 62, S_(n) = 210 ,find n and d .

If in an A.P., S_(2n)=3.S_(n) then S_(3n) : S _(n) = (a)5 (b) 6 (c)7 (d)8

In an A.P., if a = 3.5, d = 0, n = 101, then find the value of a_(n) .
