Question

please help me with this question!
if the pth term of an a.p is q and its qth term is p, then what is it's nth term?​

Answer 1

Answer:

p + q - n

Step-by-step explanation:

Let first term = a

common difference = d

pth term = q

a + (p-1) d = q  ........(1)

qth term = p

a + (q-1) d = p   ..........(2)

From 1 and 2 we get -

a = p + q - 1

d = -1

nth term = a + (n-1) d

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

              = p + q - 1 - n + 1

              = p + q - n
