<span>2t-7-5t=11
Start by combing like terms:
2-5t=-3t
Now we have:
-3t-7=11
Add 7 to both sides
-3t=18
To isolate t we divide both sides by -3
Final answer:
t=-6 </span>
The first 5 outputs are:

As you can see, the outputs keep doubling each time we increment x by 1.
This can be written formally, observing that if you know the value of
, the next value will be

So, again, we've shown that the next value is twice the previous one, so you have
