Go back the right way out (7)
I believe the answer is:
regress
'go back' is the definition.
(I've seen this before)
'right way out' is the wordplay.
'right' becomes 'r' (abbreviation).
'way out' becomes 'egress' (I've seen this before).
'r'+'egress'='REGRESS'
'the' is the link.
(Other definitions for regress that I've seen before include "Go back to earlier state, perhaps of health" , "Deteriorate" , "Go back to more primitive state" , "Get worse or go backwards" , "return journey" .)
