# Even / odd numbers

a / Using variable n write two consecutive odd numbers.
b / the sum of three consecutive odd numbers is 333. What are this numbers?

Result

a =  109
b =  111
c =  113

#### Solution:

$a) 2n, 2(n+1) \ \\ \ \\ 2n+1+2n+3+2n+5=333 \ \\ 6n=324 \ \\ n=324/6=54 \ \\ a=2 \cdot \ n+1=2 \cdot \ 54+1=109$
$b=a+2=111$
$c=a+4=113$
