If Q is an odd number and also the median of Q…

Solution:

We are provided that Q is one ODD NUMBER and that the average of Q CONSECUTIVE INTEGERS is 120. Let’s select a practically number because that Q, such together 3. We can now say:

The median of 3 continually integers is 120. Because 120 is the MEDIAN, or middle number of these integers, our 3 integers room the following:

119, 120, 121

The answer selections present us through formulas for the worth of the largest integer in the sequence. To recognize the exactly formula, we as such will plug 3 in because that Q in each answer an option until we get 121.

You are watching: If q is an odd number and the median of q

A) (Q-1)/2 + 120

(3-1)/2 + 120 = 1 + 120 = 121.

This IS same to 121.

B) 3q/2

(3 x 3)/2 = 9/2 = 4.5

This IS NOT same to 121.

C) 150q

150 x 3 = 450

This IS NOT equal to 121.

D) q/100

3/100 = .03

This IS NOT same to 121.

E) 150/q

150/3 = 50

This IS NOT equal to 121.
