Step-by-step explanation:
given = 8 - n
To calculate the first 3 terms substitute n = 1, 2, 3 into the formula
= 8 - 1 = 7
= 8 - 2 = 6
= 8 - 3 = 5
the first 3 terms are 7, 6, 5
the first negative value will occur when n > 8, that is 9
= 8 - 9 = - 1 ← first negative term

Answer:
9 and -4
Step-by-step explanation:
Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.

9(-4)
= -36
Then, check if they add up to 5:
9 + (-4)
= 5
So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5
