Im learning about Recursive and Explicit in Pre-Calc, and it says to use the rule to write the first three terms of each sequenc

Tems11 [23]

Hello,

4. you have sequences defined by the first term and a recursive relation.

$a_1=3\\\\a_n=2a_{n-1} \ \ \text{ for n}> 1$

Take n = 2, it gives

$a_2=2a_1$ , right?

But you know $a_1=3$

so $a_2=2a_1=2*3=6$

This is the second term. You are asked to find the first three terms.

Now, let's take n = 3

$a_3=2a_2=2*6=12$

So the first three terms are 3, 6, 12.

$a_1=12\\\\a_2=\dfrac{1}{2}a_1+1=\dfrac{12}{2}+1=6+1=7 \\ \\a_3=\dfrac{1}{2}a_2+1=\dfrac{7}{2}+1=\dfrac{9}{2}$

$a_1=10\\ \\a_2=-3a_1=-3*10=-30\\\\a_3=-3a_2=-3*(-30)=90$

10.

$a_1=2\\\\a_2=-1\\\\a_3=a_2+a_1=-1+2=1\\\\a_4=a_3+a_2=1-1=0$

Do not hesitate if you have any question.

Thank you

You and your friend are selling tickets to a charity event. You sell 8 adult tickets and 6 student tickets for $126. Your friend

AnnyKZ [126]

S=cost per student ticket
a=cost per adult ticket

value=(students vlue)+(adults value)
student value=(cost per student) times number of students
adult value=(cost per adult) times number of adults

you sell 8 adult and 6 students and that is a value of 126
8a+6s=126

friend sell12 adult and 13 student and get 209
12a+13s=209

so we have
8a+6s=126 and
12a+13s=209
it might help to simplify the first equaiton by dividing by 2
4a+3s=63

we have
4a+3s=63
12a+13s=209
multiply first equaton by -3
-12a-9s=-189

add to secont equaiton

12a+13s=209
<u>-12a-9s=-189 +
</u>0a+4s=20<u> </u>

4s=20
divide 4
s=5

each student ticket costs $5.00
