21-25 is -4. Is this helpful?
It's adding 7 each time. So...
5, 12, 19, 26, 33, 40, 47, 54, 61, 68, 75, and
82
A) 2 2/9
The answer would of course be positive because two negatives make a positive.
It would only be 6 4/9 if you added when here it states the obvious for you to subtract.
Hope this helped PLEASE MARK BRAINLIEST!!
