Which is an equation for the nth term of the sequence?
2 answers:
Answer: The correct option is (B)
Step-by-step explanation: We are given to select the equation that represents the nth term of the following sequence :
12, 15, 18, 21, . . .
We see that
the given sequence is an arithmetic one with first term a = 12 and common difference d given by
d = 15 - 12 = 18 - 15 = 21 - 18 = . . . =3.
We know that
the nth term of an arithmetic sequence with first term a and common difference d is given by
Therefore, the nth term of the given sequence is
Thus, the required nth term of the given sequence is
Option (B) is CORRECT.

The statement that is true about line segment P'S' is (c) Segment P'S' s 4 units long and lies on a different segment
<h3>How to determine the true statement?</h3>The complete question is in the attached image
From the image, we have:
PS = 8 units
This means that:
P'S' = 1/2 * PS
So, we have:
P'S' = 1/2 * 8
Evaluate
P'S' = 4
Also, the segment PS and P'S' do not lie on the same segment
Hence, the true statement is (c)
