Represent the numbers with

x

:

First number : x

Consecutive number 1 : x + 2

Consecutive number 2 : x + 4

Consecutive number 3 : x + 6

A.T.Q.:

6 (x + \frac{1}{3}) = 3 + 5 (- (x + 6))

Löse

6 (x + \frac{1}{3}) = 3 + 5 (- (x + 6)) : x = - \frac{29}{11}

x + 2 = - \frac{29}{11} + 2 = - \frac{7}{11}

x + 4 = - \frac{29}{11} + 4 = \frac{15}{11}

x + 6 = - \frac{29}{11} + 6 = \frac{37}{11}

Even value

- \frac{29}{11}
