a.) For examples:
n=0: A(0) = 6 +0(-3) = 6 + 0 = 6
n=1: A(1) = 6 +1(-3) = 6 – 3 = 3
n=2: A(2) = 6 +2(-3) = 6 – 6 = 0
n=3: A(3) = 6 +3(-3) = 6 – 9 = -3

a)
Explanation :
Number 6 = where the sequence starts and every next number decreases by 3 so +(n)(-3)

Depends on whether you consider the sequence to start with 0 or 1. Let’s suppose it starts with 1. If we plug that in for n, we get:
a) A(1) = 3
b) A(1) = 6
c) A(1) = 3
d) A(1) = -3
So which one gives you the right first term?

a) satisfies — first term is 6, and each successive value is 3 less than the prior
