where an= nth number

a= 1st number

n= number of integer

d= common difference

Let a=x

then

A.P. will be: x, x+d,x+2d_ _ _ _ _ _ xn

The product of the A.P. is 1

therefore the A.P. has 1 in it or half the numbers in A.P. are in fraction and the rest are whole numbers which cut them off....

Like 1/2 x 2=1

Then the A.P. must be

x. x+d, x+2d_ _ _ _ _1/x ( as xn will be the reciprocal of x such that the product becomes 1)
