EXAMPLE

a(1) = 1 steps over 1 comma to be met by the odd term 3;
a(2) = 3 steps over 3 commas to be met by the odd term 5;
a(3) = 2 steps over 2 commas to be met by the same odd term 5;
a(4) = 4 steps over 4 commas to be met by the odd term 9 (the odd term 5 is closer, but this is not the point);
a(5) = 5 steps over 5 commas to be met by the odd term 11 (again, the odd terms 7 and 9 are closer, but we don't care); etc.
