Each of five positive even numbers is $$1$$ larger than the corresponding odd number in $$1$$,$$3$$, $$5$$, $$7$$ and $$9$$, which we are told have a sum of $$25$$. So the sum of the first five positive even numbers is $$25 +5 =30$$. 
The sum of the first $$5$$ \textbf{odd} positive numbers is $$25$$. What is the sum of the first $$5$$ \textbf{even} positive numbers? 
1: $$30$$ 
2: $$35$$ 
3: $$40$$ 
4: $$45$$ 
5: $$50$$
