Triangle begins:
0;
0;
1, 0;
1, 0;
4, 0;
4, 1, 0;
9, 1, 0;
9, 1, 0;
16, 4, 0;
16, 4, 1, 0;
25, 4, 1, 0;
25, 9, 1, 0;
36, 9, 1, 0;
36, 9, 4, 0;
49, 16, 4, 1, 0;
49, 16, 4, 1, 0;
64, 16, 4, 1, 0;
64, 25, 9, 1, 0;
81, 25, 9, 1, 0;
81, 25, 9, 4, 0;
100, 36, 9, 4, 1, 0;
100, 36, 16, 4, 1, 0;
121, 36, 16, 4, 1, 0;
121, 49, 16, 4, 1, 0;
...
For n = 24 the 24th row of triangle is 121, 49, 16, 4, 1, 0 therefore the alternating row sum is 121 - 49 + 16 - 4 + 1 - 0 = 85 equaling A004125(24).
