We know that : (a - b)(a + b) = a² - b²
We know that : 1 - sin²x = cos²x
We know that : sec²x = 1 + tan²x
The question did not spesify the stating value for n.
Assuming, n = 0 is the starting value.
1st term is when n = 0:
f(0) = (0)^2 - 5 = 0 - 5 = -5
2nd term: f(1) = (1)^2 - 5 = 1 - 5 = -4
3rd term: f(2) = (2)^2 - 5 = 4 - 5 = -1
4th term: f(3) = (3)^2 - 5 = 9 - 5 = 4
Therefore, the first 4 terms are: -5, -4, -1, 4.

Step-by-step explanation:
We will follow the following steps for converting a ratio into a percentage:
Step I: Obtain the ratio. Let the ratio be x : y
Step II: Convert the given ratio into the fraction x/y.
Step III: Multiply the fraction obtained in step II by 100 and put the percentage sign(%).
