You can put this solution on YOUR website!
Let n = the number of band
members in the shortest row
The next row will have n+%2B+2 band members
The next row will have n+%2B+2+%2B+2 band members
The fourth row will have n+%2B+2+%2B+2+%2B+2 band members
given:
There are 92 band members
n+%2B+n+%2B+2+%2B+n+%2B+4+%2B+n+%2B+6+=+92
4n+%2B+12+=+92
4n+=+80
n+=+20
The shortest row has 20 members
