32 31 32 29 32 27 32.
In the above question, they added and subtracted odd numbers from 1.
So, 1 added and subtracted,1 then 3 added and subtracted 3, then 5 added and subtracted 5, then 7 added and subtracted 7.
32-1 = 31,
31+1 = 32,
32-3 = 29,
29+ 3 = 32,
32-5 = 27,
27+5 = 32,
32-7 = 25,
25+7 = 32,
Solution = 25, 32.

32 ...
