For this case the first thing you should know is that a complex number is written as follows:
a + bi
Where,
a: real part
bi: imaginary part
We note that for this case:
a = 4
b = 2
Obtaining the following complex number:
4 + 2i
Answer:
This is an example of:
a complex number

Fill in the missing number to make the sentence true ?/6 < 1/2

Ira Lisetskai [31]

Answer:

1 or 2

Step-by-step explanation:

1/6 < 1/2 (because 1/2 = 3/6 and 1/6 < 3/6)

2/6 < 1/2 (because 2/6 = 1/3 and if we convert these numbers to decimals, then 0.33 [2/6] < 0.5 [1/2])

Find the seventh term of the sequence which has a first term of 1/2 and has a common ratio of three

prohojiy [21]

The seventh term of the sequence is 364.5

<h3>Geometric progression </h3>

From the question, we are to determine the seventh term of the sequence

Using the formula,

$a_{n} = ar^{n-1}$

Where $a_{n}$ is the nth term

a is the first term

and r is the common ratio

From the given information,

a = 1/2

r = 3

Thus,

$a_{7} = (\frac{1}{2}) 3^{7-1}$

$a_{7} = (\frac{1}{2}) 3^{6}$

$a_{7} = \frac{1}{2} \times 729$

$a_{7} = 364\frac{1}{2} \ OR \ 364.5$

Hence, the seventh term of the sequence is 364.5
