Where:
You should find 
The formula to find it is:
Where d is the difference between two consecutive terms.
Then:
Substitute it into the first formula. Therefore, you obtain:
Answer:
X is 9
Step-by-step explanation:

Answer:
D. 100°
Step-by-step explanation:
A straight line is 180°. Add 50° and 30° (which is 80°) and subtract the total from 180°.
50 + 30 = 80
180 - 80 = 100
Answer:
Step-by-step explanation:
A man steps out of a plane at 4,000m of height above the ground.The point at which he jumps out of the plane would make a good reference point. However, if his acceleration is going to change as a result of him opening his parachute 2000m above the ground, a good reference point would be there. Keep in mind though, that his velocity at that instant would need to be known for it to be useful- otherwise the airplane reference point would be just as good with appropriate modeling....
Percent change = ((new value) - (old value))/(old value) × 100%
= (30 - 32.5)/32.5 × 100%
≈ -8%
