You would have the equation 2x+1=67.
Then you would -1 from each side so it would give you 2x=66
The you would divided each side by 2 then it would give you x=33
Since they are consecutive it would either be 1 larger number than 33 or 1 smaller number.
The second number would be 34 because when 33 and 34 are added together it would equal 67
