The difference between the reciprocal of two consecutive odd numbers is 2 / 143. What are the reciprocal of these two consecutive odd numbers?

Let an odd number be x, then the other odd number be x + 2
Then 1 / X-1 / (x + 2) = 2 / 143
x(x+2)=143
(x+1)^2=144
x+1=12 =-12
x=11 =-13
The reciprocal is 1 / 11, 1 / 13
Or - 1 / 13, - 1 / 11
