The median of a set of consecutive odd intergers is 138. If the greatest integer in the set is 145 what is the smallest integer in the set?
I DONT KNOW :O
Hello, xsriel!
You can baby-talk your way through this one . . .The median of a set of consecutive odd integers is 138.
If the greatest integer in the set is 145 what is the smallest integer in the set?
We have consecutive odd integers, like: .
If 138 is the median, it is in the "middle" of the set of integers
. . (with an equal number of integers on both sides).
. .
. - - . . . . . . . . . . . . . . . . .
. . . . . . . . . . . . . . . . . . .
Since the largest number is 145, the sequence looks like this:
. .
. - . - . . . . . . . . . .
Therefore, the smallest integer is 131.
