Answer:

For 7, r=4.1, and for 8, r = 8.7

Step-by-step explanation:

r is the distance from the center point to anywhere in the circle, meaning that (assuming C is the center point), You just take the length of the side from C to the other points in the circle.

Which formula decribe the following geometric equence? Remember that n repreent the term number. 2, 6, 18, 54,. An = 3 · 2 n - 1

Goryan [66]

For the given geometric progression, the nth term of the given GP is $A_n=2.3^{n-1}$ .

Option (C) is correct.

What is the Geometric Progression?

Geometric Progression (GP) is a type of sequence in mathematics in which each succeeding term is produced by multiplying each preceding term by a fixed number known as a common ratio. This progression is also known as a pattern-following geometric sequence of numbers.

The given sequence is 2, 6, 18, 54

here the first term(a) = 2 and the common ratio(r) = 6/2 =3

Then by using the formula for the nth term of a GP, we get

$A_n=ar^{n-1}\\\\A_n=2.3^{n-1}$
