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

131 perhaps start with 131 go to 145. 138 is the median. i could be wrong, but i think that's right

Hello, xsriel!

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.
