Question

In an A.P. ,the $p^{th}$ term is q and $(p+q)^{th}$ term is 0 then $q^{th}$ term is?

Answer 1

Answer:

p

Step-by-step explanation:

Going by the formulae of Arithmetic Progressions,

a+(p-1)d = q ........ (1)

a+(p+q-1)d = 0 ....... (2)

From 1 and 2 we can observe that,

d = -1 and a = q+p-1 ,

So qth term = a+(q-1)d = p+q-1-1-q = p
