Find n and d if `a=8 a_n=62 S_n=210`

Let there be an A.P. with first term ' a ' , common difference ' d ' . If a_n denotes its n t h term and S_n the sum of first n terms, find n and d , if a=8,\ \ a_n=62 and S_n=210 .

Let there be an A.P.with first term 'a' common difference 'd'. If a_(n) denotes its nth term and S_(n) the sum of first n terms,find n and d, if a=8,a_(n)=62 and S_(n)=210

In an AP: given a=8, a_n=62,S_n=210 find n and d

In an A.P, a=8 , t_n=62 , S_n=210 , then find n . a) 5 b) 6 c) 7 d) 8

In an AP :- given a = 8, a_n = 62. S_n =210, find n and d .

In an AP:(vii) given a=8, a_n=62,S_n=210 ,find n and d
