Dear sougata

Ist question is not clear

2nd question:


let first term is =a  and common difference =d

p =a+(q-1)d  ............1

q =a+(p-1)d  ..............2


1-2

p-q = (q-p)d

d =-1

put value of d in equation 1

a =p+q -1


now p+q th term  = a+ ( p+q -1)d

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

                        =0
