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

Let the smaller odd number be n, then the other odd number is n + 2
1 / n-1 / N + 2 = 2 / 143, the solution is n = 11,
So the reciprocal is 1 / 11 and 1 / 13, respectively
