Answer(s):

3. Option B

4. Option D

Step-by-step explanation:

<u>Question 3:</u>

2/3 = 1.2/x
=> 2 × x = 1.2 × 3
=> 2x = 3.6
=> x = 3.6/2
=> x = 1.8 [Option B]

<u>Question 4:</u>

8/15 = 24/x
=> 8 × x = 24 × 15
=> 8x = 3 × 8 × 3 × 5
=> 8x = 9 × 40
=> 8x = 360
=> x = 360/8
=> x = 45 [Option D]

The 6th term of the geometric sequence is of -4096.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

In which $a_1$ is the first term.

For this problem, we have that:

The first term is $a_1 = 4$ .

$a_n = -4a_{n - 1}$ , hence the common ratio is q = -4.

Thus the 6th term of the sequence is found as follows:

$a_6 = a_1q^5 = 4(-4)^5 = -4096$

31 + 35 = 66

66/2 = 33
