Find the pattern for each sequence and then use the pattern to show the next two terms. 1. 45, 40, 35, 30, 25, ...
2. -3, 6, -12, 24, -48, ...

1.an=45+(n-1)-5

2.Gn=-3r^n-1

Step-by-step explanation:

Check for answer 1

Take n=2 a2=45+(2-1)-5=40

Take n=3 n3=45+(3-1)-5=35

Check for answer 2

Take n=2 G2=-3×-2^1=6

Take n=3 G3=-3×-2^2=12

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
