Help with math plz! Giving brainlist

First one, 

You add -7 to the pattern. 

5, -2, -9, -16.
50 times is going to be -350. But it starts at 5, so you add 5 to -350... so it should be -345?

second if the top is 7.1 and the bottom is 3.9. The average is (7.1+3.9)/2.
11/2 = 5.5

Add 10 to each number in the pattern.
-7, 3, 13, 23. 
110 times should be 1100, but it starts at -7, so you add -7 to 1100. 1093. :)
