Which of the following is the algebraic expression that best descibes the sequence 7, 14, 21, 28 ?

The algebraic expression that best describes the following sequence is +7 every time. Because, 7+7=14, 14+7=21, 21+7=28.

If you would like to get from term to term number, you multiply by seven every time. term 1x7=7, term 2x7=14, term 3x7=21.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
