What is a formula for the nth term of the given sequence? 48, 72, 108

WITCHER [35]

Answer:

$a_n=48*1.5^{n-1}$

Step-by-step explanation:

<u>Geometric Sequence</u>

In geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the sequence:

48, 72, 108, ...

The common ratio is found by dividing the second term by the first term:

$r=\frac{72}{48}=1.5$

To ensure this is a geometric sequence, we use the ratio just calculated to find the third term a3=72*1.5=108.

Now we are sure this is a geometric sequence, we use the general term formula:

$a_n=a_1*r^{n-1}$

Where a1=48 and r=1.5

$\boxed{a_n=48*1.5^{n-1}}$

For example, to find the 5th term:

$a_5=48*1.5^{5-1}=48*1.5^{4}=243$

What is the slope intercept form of the points -3,-10 and 5,14

Ksenya-84 [330]

Answer:

y = 3x - 1

The slope intercept is -1.

To find the slope, do the formula (y sub2 minus y sub1)/(x sub2 minus x sub1) then reduce.

(14 - (-10))(5 - (-3)) = 24/8

24/8 = 3

Find a formula for the inverse g (x) =(x-1) ^1/3-1

katrin [286]

Y= x+ (x-1) ^1/3-1
y+1=x+(x-1) ^1/3
(1/3)1/3=0
y+1(1/3)= x+(x+1)
y/3=x+(x+1)
y/3=2x+1
(y/3)(2/1)=x+1
2y/3-1=x
g(x)= (2y/3-1)⁻⁻¹
