<h3>Arithmetic sequence:</h3>
In a arithmetic sequence, difference between any two consecutive term is constant.
a₁ = 9 & d = 7
t₁ = 9
t₂ = a₁ + d
= 9 + 7
= 16
t₃ = t₂ + d = 16+ 7
= 23
t₄ = t₃ + d
= 23 + 7
= 30
t₅ = t₄ + d
= 30 + 7
= 37
9,16,23,30,37,.......
an =a1+ d(n-1)
a1 = 1st term = 3
d = common difference = 7-3 = 4
an = 3 + 4(n-1)
n= term interested in
a37 = 3 + 4(37-1)
a37 = 3+4*36
a37 = 3 +144
a37 = 147

Answer:
Option D.
Step-by-step explanation:
A reflection is a mirror image across the a line of reflection. The image will be perpendicular to the line of reflection and equal distance from it as the pre-image is too. This means that point G will move horizontally across the y-axis the same distance it is currently from the y-axis. It is 2 units away from the y-axis so G' will be 2 units on the other side or -2. This makes G' (-2,2). Notice this is the same coordinates of G only multiplied by -1. When reflecting a shape across the y-axis, the x-coordinates of the points are multiplied by -1.
So G (2,2) becomes (-2,2).
So F (-2,-1) becomes (2,-1).
So H (4,-3) becomes (-4,-3).
