At the end of this passage I have realized a figured bass with an ascending line using melodic minor. I am instructed to use 10ths in the outer voices for bar 5 so I obviously will have ^6 in the soprano for the IV chord. If I am to have the line ascend from this point it should use the melodic minor scale and ^6 will need to be raised to give me a major IV instead of a minor iv. However this produces a large leap of a diminished 5th. It does change direction but I'm not sure of this would be acceptable or not. My textbook does say dissonant leaps are good if the line changes direction but not sure about this one.
Edit: Here is another solution without using raised ^6.
