Use math induction proof method will be usefully
for n=1 will get
1^2 = 1(6*1^2 -3*1 -1)/2
1 = 1(6-4)/2
1 = 1(2)/2
1 = 1
suppose true for n=k and prove for k = k+1
hope this will help you

Answer:
184 students
Step-by-step explanation:
This is a simple question where we want to find 80% of 230.
Firstly, we have to convert 80% to decimal. For that, we have to divide by 100. Thus,
80% = 80/100 = 0.80
Now, to find 80% of 230, we have to multiply 80% (0.80) with 230 and do the math. Hence,
0.80 * 230 = 184
Thus,
we can say that 184 students have had algebra.
