Hi!
What you'll first need to do is subtract 4 from 4 and 13. After doing so, your equation will look like this...
-3x=9
Next, you'll need to divide -3x and 9 by -3. After you've done that, you'll get...
x=-3.
So your answer would be x=-3
I hope this helps!
First term = T(1) is obtained by plugging n = 1 into the formula,
thus First term = 1^2 - 4 = 1 - 4
= 3 (answer)
