Answer:

a(n) = a(n-1) + 4

Step-by-step explanation:

a(1) = 2 The first term is 2

a(n) = a(n-1) + 4 We add 4 to the previous term or n-1

So, we get...

a(n) = a(n-1) + 4

a(1) = 2

a(2) = a(2-1) + 4 2(1) +4 = 6

a(3) = a(3-1) +4 3(2) + 4 = 10

and so on and so forth. I hope this helps.

Algebra problem help

True [87]

To solve this problem you must apply the proccedure below:

1. You have that one canned juice drink is 20% orange juice and another is 5% orange juice.

2. You must make a system of equation, as below:

x+y=15 (i)
0.20x+0.05y=0.15x15 (ii)

3. Now, you must find the value of x (the liters of the first canned needed) and y (the liters of the other canned needed):

x+y=15 (i)
x=15-y

0.20x+0.05y=0.15x15 (ii)
0.20(15-y)+0.05y=2.25
y=5 liters

x+y=15 (i)
x=15-5
x=10 liters

4. Therefore, the asnwer is:

10 liters of the canned juice drink that is 20% orange juice and 5 liters of the other canned juice drink that is 5% orange juice.
