Answer 1

I tried to do this in class but im having a hard time doing the maze :<

Answer 2

Arithmetic sequence formula:

an = a1 + (n-1)d

a1 is always your first term in the list
n = how many terms there are
an = the nth term. So for an example, a5 means the 5th term.
d = common difference (how much is it increasing or decreasing each time?)

From the starting box, (-31, -42, -53, -64), your first term is -31 since it’s first in the list, so a1 = -31. It’s decreasing by 11 each time (-31 - 11 = -42, and so on for the rest of the list) so d = -11. It wants a11 so n = 11

Plugging this into our formula: -31 + (11-1)(-11) = -141 so you would fill -141 into the purple box left of this problem and go to the box along that path (top row middle box), repeat the process for the rest of the maze
