First, since we must follow PEMDAS, we need to do the operation that is first, which is addition.
-3.9 + 6.01 ← Adding a negative means subtracting, then giving the sign of the bigger number.
So now we solved those and we got this answer: 2.11
Now, we need to subtract and re-write the expression.
2.11 - (-7.423) = 2.11 + 7.423= 9.533
Ok....so now we have our final answer, and we have the choices above.
The only answer that matches ours is the last one.
Final answer: 9.533

Answer:
an = 7.5 - 5.5(n - 1).
Step-by-step explanation:
The common difference d = -5.5.
The first term is given as 7.5.
Explicit formula is
an = a1 + (n - 1)d
= 7.5 + (n - 1)-5.5
= 7.5 - 5.5(n - 1)
