    Question [SOLVED] Whole consecutive numbers

    The problem states:

    Find 4 consecutive whole numbers such that the sum of the first three numbers equals the fourth number.

    Ok, so heres how I think it should be:

    x = 1st #
    x+1 = 2nd #
    x+2 = 3rd #
    x+3 = 4th #

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

    Now if this is correct then this is how it works out...

    3x+3=x+3
    2x+3=3
    2x=0

    Now this is where Im stumped. Any help would be appreciated.

    Find 4 consecutive whole numbers such that the sum of the first three numbers equals the fourth number.

    set of whole numbers is {0, 1, 2, 3, ... }

    0+1+2 = 3

    works for me.

    Yes your equation is correct.
    2x = 0
    means x = 0

    and we have assumed that numbers are x, x + 1, x + 2, x + 3
    so numbers are 0, 0+1,0+2,1+3
    i.e. 0, 1, 2 and 3.

    Most of the time, if you follow basics correctly, problems will be solved easily. Maths is very rational subject.

    Keep Walking Bro.
