1÷81 because you square it
You did a simple mistake by forgetting to add 4 to itself in the square root. (-4^2=16)
x=(4 +/- sqrt(16-8))/4
x=(4 +/- sqrt(8))/4
Is this enough to get you started again?
Answer:
- f(1) = 4
- f(n) = f(n - 1) + 4
Step-by-step explanation:
Given the sequence:
The first term is 4 and common difference is 4
<u>Recursive formula:</u>
- f(1) = 4
- f(n) = f(n - 1) + 4
