So you know how to solve it?
I need to know what process you have used, only then can i tell you whether im doing the same or using a new way...
N
Ratio leke kre raha hu
@THE DUDE Yoo, As per the formula, sum of n terms = n(2a+ (n-1)d)/2. for the ap we will consider the first term as a and the common difference as d.
Its a single AP only
ooff sorry then
substitute them in the formula where m(2a+ (m-1)d)/n(2a+(n-1)d) = m^2/n^2 where i believe m and n can get cancelled. so 2a+ (m-1)d/2a+(n-1)d= m/n
cross multiply and I believe you will get 2an+ mnd-nd +2am+mnd -md where it then becomes 2an-2am= dn-dm which becomes 2a(n-m)= d(n-m) which gives ya 2a=d
sub this thing in the formula an = a+(n-1)d and you will get the ans ()since this is text it mught be hard to understand
copy pen pls
tbh you will alr know how to do the q but you get worried and doubt yourself as soon as you see the q, honestl these qs look tricky but r easy but a little tedious thats all.
