Answer 4

Sorry, I was helping someone else with a similar problem and I was using their data. Sorry again.

-7,3,13,23

This is an arithmetic sequence since there is a common difference between each term. In this case, adding 10 to the previous term in the sequence gives the next term. In other words, an=an-1+d.
Arithmetic Sequence: d=10

Reorder the polynomial n-1 alphabetically from left to right, starting with the highest order term.
an=-7+10(n-1)

Multiply 10 by each term inside the parentheses.
an=-7+(10n-10)

Subtract 10 from -7 to get -17.
an=-17+10n

Reorder the polynomial -17+10n alphabetically from left to right, starting with the highest order term.
an=10n-17

Multiply 10 by each term inside the parentheses.
a110=1100-17

Subtract 17 from 1100 to get 1083.
a110=1083
