Select the function that represents a geometric sequence.
O
A. A(n) = P(1+1)-1, where n is a positive integer
O
B. A(n) = (n - 1)(P. n)', where n is any real number
C. An) = + (-1). P, where n is a positive integer
O
O
D. A(n) = P + (n-1);• P, where n is a positive integer

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

the answer

b. they are parallel and will never intersect.

squares, rhombus, rectangles
