7. It's helpful if we can find a general "formula"
One possibility is :
an = -7 + 10 ( n - 1)
So term 110 is just
-7 + 10 (110 - 1) =
-7 + 10 (109) =
1083
8. Note, NSS...looking at the last two terms, it appears that we are subtracting 5 from the previous term to get the next term
So.....second term = -7 - 5 = -12
And....third term = -12 - 5 = -17
