Answer:
39 is the 13th term
Step-by-step explanation:
Okay so essentially the is just a substitute for x.
See how in the equation they put n into the x spot:
They changed the variable names:
Now we know what the n actually means, plus when they ask about the terms youre trying to find it's based off of that n:
When they say, 13 term, they mean which would be the 13th answer in the series. So the first term would be based off of
So whatever number is in the n position by a is what you'll be plugging into the x spot.
These are all the answers leading up to the 13th term they asked for, and you can continue thus same equation with whatever number you can put into the n space.
If you have a fraction, then the denominator (bottom) cannot equal 0, since it is impossible to divide by 0. Take a look at the function below.
If we plugged in 2 for x, we would end up with a denominator of 0, making x = 2 "extraneous."
(you can use this example to answer your question, with the denominator being x-2...any expression that evaluates to 0 when x = 2 would work)
