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

Correct answer:

a =  109
b =  111
c =  113

Step-by-step explanation:

$$\begin{gathered} a)2n,2(n+1) \\ 2n+1+2n+3+2n+5=333 \\ 6n=324 \\ n=324\mathrm{/}6=54 \\ a=2\cdot n+1=2\cdot 54+1=109 \end{gathered}$$

$b=a+2=111$

$c=a+4=113$
