Use the formula: (a - b)^2 = a^2 - 2ab + b^2.
=> (5s - 3)^2 = (5s)^2 - 2(5s)(3) + (3)^2 = 25s^2 - 30s +9
The list of options is mistyped, so you must use the right list of choices and find which is 25s^2 - 30s + 9.
Answer: 25s^2 - 30s + 9

Answer:
an = -6n + 5.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 = -1 and common difference d = -6
an = a1 + d(n-1)
an = -1 + -6(n - 1)
an = -1 -6n + 6
an = -6n + 5.
