What is the next term in the sequence?
1,-3,9,-27

Begin by studying the pattern.

Here, notice that 1 × -3 is equal to -3.

-3 × -3 is equal to 9.

9 × -3 is equal to -27.

Continuing the same pattern, -27 × -3 is equal to 1.

So the next term in the pattern is 81.

So, we multiply by -3 each time.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
