Remember that ratios are essentially fractions without fraction bars...
If they asked to find the ration of 19.50 to 16.25 you would set them up like so....
19.50 : 16.25 -----> since fractions can be simplified so can ratios in the same manner
the ratio you would end up with is <u>6 : 5</u><u />
Ratios can be easily remembered and solved if you understand the link between them and fractions.
I hope this helps! :D

Answer:
Step-by-step explanation:
Positive integers are of the form 2n
The first term is 2 and the 130th term is 2(130)=260

(2+260)(130/2)
17030
