$17.92 is the total before tax. The tax price was $1.16. After tax the total is $19.08
The negative sign isnt changing back and forth, so its not a geometric sequence
the difference between each term looks to be constant at 10
a1= 3
a2=-7= a1-10
a3= -17 =a2-10
oh look a pattern
an= a(n-1) - 10
You'll have to substitute all the y's by 18, so our expression will stay like this:
18 - 2 =
16 = final answer

2•2=4 + 2•2=4
4+4=8
