straightforward way is to write an equation x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 372 and to solve it. That unique solution "x" will be your answer. The more reasonable way is to divide 372 by 6, = 62. Then the three consecutive odd numbers in the DESCENDING order from 62 are 61, 59, 57, giving you the answer 57.
