Consecutive Number Problems If the numbers are consecutive use: 1stnumber = x 2ndnumber = x + 1 3rdnumber = x + 2 etc
Consecutive Number Problems If the numbers are consecutive ODD: 1stnumber = x 2ndnumber = x + 2 3rdnumber = x + 4 etc
Consecutive Number Problems If the numbers are consecutive EVEN: 1stnumber = x 2ndnumber = x + 2 3rdnumber = x + 4 etc
