Question

If the p th term if an A.P is q and the q th term is p, prove that its n th term is (p+q-n).......​

Answer 1

Answer:

Explanation:

let the first term be a and common difference be d,

p th term,

=a+(p-1)d,

=q⇒i,

q th term,

=a+(q-1)d,

=p⇒ii,

ii-i gives,

(q-p)d=p-q ord=-1,

i gives a,

=q-(p-1)d,

=q-(p-1)(-1),

=q+p-1,

Hence,

n th term,

=a+(n-1)d,

=q+p-1+(n-1)(-1),

=q+p-1+n+1,

=p+q-n,proved.

Hope it helps.
