Just make a triangle and an X and Y axis and reflect it over the Y axis. It's that simple. Then tell how you did it. Obviously it will be a reflection. Name the points (before and after) and you are done.

Answer:
the first five terms are
a1 = 6
a2 = 24
a3 = 60
a4 = 120
a5 = 210
Step-by-step explanation:
the experission used to find the five terms is
an = n3+ 3n2+ 2n
You can use the sum and difference identities which for cosine is cos(a+b)= cosacosb-sinasinb
1/6(36 + 1/2) = 6 + 1/12 = 72/12 + 1/12 = 73/12
