Find the next two terms of the sequence: 80, ? 40, 20, ? 10, a) 20, 40 b) 1 2 , 1 4 c) 5, ? 5 2 eliminate d) ? 30, ? 40

5, 5/2

Step-by-step explanation:

80 becomes 40 if multiplied by 1/2; 40 becomes 20 if mult. by 1/2; and so on.

Thus, the common ratio of this geometric sequence is 1/2.

1/2 times 10 is 5;

1/2 times 5 is 5/2.

Looks like this is Answer C.  Please note:  your "5, 5 2" is not a correct representation of "5, 5/2."  Please use " / " to indicate division.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
