   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules.
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

let median be x, the first three numbers will be x-1, x-1, x

wait let me check something

assumed there is only one mode

and the mean is x+1

[rapid trellis]

i ended up with this equation and dont know what to do now

with median as c

[indigo wasp]

you want to maximize e

while keeping d larger than c

this will give you d = c+1 and e = c+6

[rapid trellis]

why +6

[indigo wasp]

you want to maximize e, so you want to minimize d

but d > c

therefore d is c+1

[indigo wasp]

and d+e = 2c+7 so e is found through this

[rapid trellis]

wait why do we add only 1 to d? we want it to be as close to c as possible so the smallest it can be while being bigger than c?

[indigo wasp]

yes

[rapid trellis]

ohh okay why do we minimise d

[indigo wasp]

because we want e to be as big as possible

[rapid trellis]

ohhh

[indigo wasp]

and d+e is constant

[rapid trellis]

ohhhhhhhhh

because d+e is equl to one number and if

d is as small as possible

[indigo wasp]

yes

[rapid trellis]

e will be as large as possible

omg that makes so much snese

[indigo wasp]

so the range ends up being 7

(c+6) - (c-1)

[rapid trellis]

then we can find largest range by having largest e

[indigo wasp]

yes

[rapid trellis]

ahh that makes sense thank you so much

@rapid trellis has given 1 rep to @tender bobcat

[indigo wasp]
