ListCorrelate[{1, 2, 3, 4}, {a, b, c, d, e},
  1, 1, Power[#2, #1] &, Plus][[{1, 2}]]

{a + b^2 + c^3 + d^4, b + c^2 + d^3 + e^4}

It is easy to use ListCorrelate to generate the sum of a list

d,b+2 c+3 d+4 e}.  Is there any way, using the optional 5th and 6th
parameters, to generate this list instead:
