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

How much pure acid should be mixed with 6 gallons of a 20% acid solution in order to get a 40% acid solution

Misha Larkins [42]

Let A be the amount of 100% acid.

100A+20*(6)=40*(A+6)

100A+120=40A+240

60A=120

A=2 gallons

If two acute angles of a right angled triangle are in the ratio 1:2, Find them.

Anarel [89]

Answer:

30°,60°,90°

Step-by-step explanation:

Let :-

Ratio = 1x : 2x

As we know :-

Sum of all angles = 180°

So that ,

x + 2x + 90 = 180
3x = 90
x = 90/3
x = 30

Angles ,

90°
x = 30°
2x = 60°
