Write an explicit formula for the An, and the n^th term of the sequence 24,-12,6,....
Annette [7]

Answer:

T_n =  -48* (-\frac{1}{2})^{n}

Step-by-step explanation:

Given

24, -12, 6,...

Required

Write a formula

The above sequence shows a geometric sequence because:

r = \frac{-12}{24} = \frac{6}{-12} = -\frac{1}{2} -- common ratio

The equation is determined using:

T_n = ar^{n-1}

Where

a = 24

Substitute values for a and r

T_n = 24* (-\frac{1}{2})^{n-1}

Apply law of indices:

T_n = 24* (-\frac{1}{2})^{n} * (-\frac{1}{2})^{-1}

T_n = 24* (-\frac{1}{2})^{n} * 1/(-\frac{1}{2})

T_n = 24* (-\frac{1}{2})^{n} * 1*-2

T_n =  1*-2*24* (-\frac{1}{2})^{n}

T_n =  -48* (-\frac{1}{2})^{n}

<em>The above represents the explicit formula</em>

If g stands for a whole number, find the first three possible values of g2 + 3.
Sati [7]

So the first three possible values of g^2 + 3 are:

3, 4, 7

The first option is the correct one.

<h3>Which ones are the first three possible values?</h3>

The set of the whole numbers is {0, 1, 2, 3...}

Then the first possible value is when g = 0.

0^2 + 3 = 3

The second possible value is when g = 1

1^2 + 3 = 4

The third possible value is when g = 2.

2^2 + 3 = 7

So the first three possible values of g^2 + 3 are:

3, 4, 7

The first option is the correct one.
