Example

Group the digits of Pi as follows: (3), (1,4), (1,5,9), (2,6,5,3), (5,8,9,7,9), etc., and take the sum of each group. Thus, the first five terms of the sequence are: 3, 1+4=5, 1+5+9=15, 2+6+5+3=16, and 5+8+9+7+9=38.

Mathematica

Module[{nn=100, pid}, pid=RealDigits[Pi, 10, (nn(nn+1))/2][[1]]; Total/@ TakeList[ pid, Range[nn]]]
