Answer 1

Hey man this is a simple question

I request U to plz solve ncert before attempting such questions (If u are in 11th)

Here is the answer for the question

see

Acc. to question

q=a+(p-1)d

p=a+(q-1)d

Further open it

q=a+pd-d

p=a+qd-d

Subtract the above two equations

we will get d as -1

and now put d=-1 in the above equation

we will get a as p+q-1

Now to find the nth term

a+(n-1)d

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

p+q-1-n+1

We get

p+q-n

I hope this helps
