Question

which of the numbers below is the sum of four consecutive whole numbers


A) 15
B) 2000
C)2002
D)2004
E)2005

Answer 1

NUMBER = x + (x+1) + (x+2) + (x+3)

NUMBER = 4x + 6

NUMBER - 6 = 4x

x = (1/4)(NUMBER - 6)

x should be an integer (a whole number) for only one of the 5 options. the NUMBER of the 5 choices that you used to get an integer is your answer
