2y+6,3y and y4 are all integers and y4 is the median of these intergers which of the following could not be value of y?

2y+6,3y and y4 are all integers and y4 is the median of these intergers
=>
case 1:
2y+6≥y4 AND 3y≤y4
2y+6≥y4 => y≥10
AND
3y≤y4 => y≤2
=>
10≤y≤2
or case 2:
2y+6≤y4 AND 3y≥y4
solving similarly,
2≤y≤10
which is impossible.
Now you only have to figure out the invalid choice from your list.
