Which sequence is a geometric progression?
A 2 4 6 8
B 1 1 2 3
С 1 2 4 8
D 1 3 5 7

c) 1 2 4 8

Step-by-step explanation:

Explanation :-

Geometric sequence

The sequence is of the form a , a r , a r² , a r³ ,.......

'a' is the first term

'r' is the common ratio

1 , 1(2) , 1( 2)² , 1( 2 )³ ......  is a geometric sequence

here a = 1

common ratio  

The sequence 1 2 4 8 is a geometric sequence

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

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
