The formula for a geometric sequence is an = a1 * r^n-1. For this problem, our formula can be an = 1 * 5^n-1. a1 is our first term, and r is the common ratio.
To check our formula, we can find the 5th term. a5 = 1 * 5^5-1. This gives us 625. If we look at our last term provided, the 4th term, 125 * 5 is 625.
Answer:
Well from all the exams and assignments I've had, 100 points is the full grade so losing 100 points would mean you would fail with a 0
I hope this helps you
(square root of 2x^2-3x)^2=0^2
2x^2-3x=0
x (2x-3)=0
x=0
2x-3=0
x=3/2
