1. this is a series of squares Formula is an = n^2
2. Arithmetic series with common difference d = -2.
an = a1 + (n-1)d = 3 -2(n-1)
Cant see the rule for Number 3
Step-by-step explanation:
horizontal lines will have a gradient(m) of 0
so if m=0 , the line is horizontal
formula to find m:
m=y2-y1 / x2-x1
insert coordinates into formula

As m=0 , therefore it is a horizonta line.
hope this helps..
