Answer 1

1. 98.8 2. 194 3. 49 2/3

Explanation:

I found the pattern of each of them

Here is the math I did for the 1st one: 1.3(1st number)+2.5*39(pattern times one less than the term number you want)=98.8

This is actually the first time I have done this, so I this should help both of us!!! Me with learning more math, and you with doing your own math.
