A=[45 48 63 84 32]

B=[272 227 179 116 32]

A is matrix which has some randm numbers, Matrix B is answer

Logic is, we have to start sum from last element that is 32

last second element in answer (B) is 32+84 = 116

last third element in answer (B) is 32+84+63 = 179

last fourth element in answer (B) is 32+84+63+48 = 227

last fifth element in answer (B) is 32+84+63+48+45 = 272 and so on...
