Answer:
For an nth term U(n) = a + ( n - 1)d
n = number of terms
a = first term
d = common difference
a = -9
d = -3--9 = -3+9 = 6
U(n) = -9 + (n - 1)6
That's option A.
Hope this helps.

Answer: a=−3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
a−2+3=−2
a+−2+3=−2
(a)+(−2+3)=−2(Combine Like Terms)
a+1=−2
a+1=−2
Step 2: Subtract 1 from both sides.
a+1−1=−2−1
a=−3
