Math Problem Statement
给定的数列: 1/1, 2/1, 1/2, 3/1, 2/2, 1/3, 4/1, 3/2, 2/3, 1/4, ...
我们可以发现以下规律:
- 分子和分母的值交替递增和递减。
- 分子和分母的和是递增的。
- 分子和分母的差的绝对值是循环递增的: 0, 1, 1, 2, 0, 2, 3, 1, 1, 3, ...
现在,我们来尝试找出这个数列的通项

S = n + m, where n and m represent the numerator and denominator
T(S) = (S(S-1))/2, to calculate the cumulative number of terms
Numerator = S - (k - T(S))
Denominator = k - T(S)
