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)/218​

Answer 1

Answer:

hiii bro

here is ur answer

pth term = q

a+(p−1)d=q

qth term = p

a+(q−1)d=p

Solving these equations, we get,

d=−1

a=(p+q−1)

Thus,

nth term = a+(n−1)d=(p+q−1)+(n−1)×(−1)=(p+q−n)
