Answer:
4
Step-by-step explanation:
an=-4+3(n-1)=-4+3n-3=3n-7
a1=3×1-7=3-7=-4
a5=3×5-7=15-7=8
a1+a5=-4+8=4
Y = -4x

15 is 6 because 12 divided by 2 is 6
19 is 12 because 12-3 is 9
In this problem, you have to find the total profit the company made in the three quarters which makes up 3/4 of the whole. In the second quarter, the profit is 4 million. Let x be the profit in the first quarter. Following the description,
4 = (1+1/3)x
x = 3 million
Thus, the second quarter made 5.33 million profit.
For the third quarter, let's assign it to the y variable. Following the description,
4 = (4/5)(y)
y = 5 million
Thus, the total profit is 4 + 3 + 5 = 12 million
