Easy question :)

What is the next term in the sequence below?

0.25, 0.75, 2.25, 6.75, …
A. 6.25
B. 10.25
C. 20.25
D. 60.75

Respuesta :

C. because 2.25 X 3 = 6.75 and 6.75 X 3 is 20.25

A geometric sequence is characterized by a common ratio.

The next term of the sequence is 20.25

First, we calculate the common ratio (r)

[tex]\mathbf{r = \frac{T_2}{T_1}}[/tex]

So, we have:

[tex]\mathbf{r = \frac{0.75}{0.25}}[/tex]

[tex]\mathbf{r = 3}[/tex]

The nth term of the GP is calculated using:

[tex]\mathbf{T_n = T_1 \times r^{n-1}}[/tex]

Where:

[tex]\mathbf{T_1= 0.25}[/tex]

[tex]\mathbf{n = 5}[/tex]

So, we have:

[tex]\mathbf{T_5 = 0.25 \times 3^{5-1}}[/tex]

[tex]\mathbf{T_5 = 0.25 \times 3^4}[/tex]

[tex]\mathbf{T_5 = 20.25}[/tex]

Hence, the next term of the sequence is 20.25
