Step-by-step explanation:

to know whether it is geometric progression or not, you need to find the common ratio. to find the ratio divide the (n+1)th term by n th term

so, 12/-4 = -3

also, -36/12 = -3

here u see the ratio is always same, i.e., common ratio.

thus u can say it is a geometric series with common ratio -3

A sphere has a diameter of 14.5 inches.

dlinn [17]

Answer:

≈ 660.5 in²

Step-by-step explanation:

The surface area (A) of a sphere is calculated using the formula

A = 4πr² ← r is the radius

Given diameter = 14. 5 then radius = 7.25, thus

A = 4π × 7.25² = 4π × 52.5625 ≈ 660.5 in²

Please help me Katie keeps deleting my questions but idk why?

Answer:

Pattern seen is arithmetic progression. The both equations are same.

Step-by-step explanation:

a.The given pattern is 8,12,16,20,24....We can see that the difference between any two consecutive terms is 4.Therefore this is an AP(arithmetic progression).

b.Percy's equation , $N = 8 + 4(s-1)\\$

⇒ $N = 8 + 4s - 4$

⇒ $N = 4s + 4$

⇒ $N = 4(s+1)$

which is the same as Stella's equation . So , we can see that both equations are the same.
