Answer 2

Answer 3

\(\large\color{slate}{ a_n=\frac{1}{2}a_{n-1} +4 }\)

\(\large\color{slate}{ a_1=16 }\)

(by the way, you can use ~ as a space.)

\(\large\color{slate}{ a_2=\frac{1}2(16) +4=12 }\)

\(\large\color{slate}{ a_3=\frac{1}2(12) +4=10 }\)

Answer 4

the pattern doesn't seem to be either geometric or arithmetic,
what i would do is just to follow what I did for the 4th and the 5tf term

Answer 5

5th*

Answer 6

seems like it is:
subtract 4
subtract 2
subtract 1

and on...
