<h2>The answer is Option A!</h2>
<h3>Why so??</h3>
Let's see what complex numbers are!
Now we know,
So!
And thus we get the answer!
The number of terms in the given arithmetic sequence is n = 10. Using the given first, last term, and the common difference of the arithmetic sequence, the required value is calculated.
<h3>What is the nth term of an arithmetic sequence?</h3>
The general form of the nth term of an arithmetic sequence is
an = a1 + (n - 1)d
Where,
a1 - first term
n - number of terms in the sequence
d - the common difference
<h3>Calculation:</h3>
The given sequence is an arithmetic sequence.
First term a1 = = 3/2
Last term an = = 5/2
Common difference d = 1/9
From the general formula,
an = a1 + (n - 1)d
On substituting,
5/2 = 3/2 + (n - 1)1/9
⇒ (n - 1)1/9 = 5/2 - 3/2
⇒ (n - 1)1/9 = 1
⇒ n - 1 = 9
⇒ n = 9 + 1
∴ n = 10
Thus, there are 10 terms in the given arithmetic sequence.

Answer Answer Answer Answer
Answer:
they are all expressions except D) 6y + 1z = 7x - 3w which is an equation, B
4x ^ 2

- 6 it is not known because it is poorly written.
Step-by-step explanation:
Which of the following is NOT an expression?
A 3x + 1 (expression)
B 4x^2 2- 6 (unknow)
C) 5b (expeession)
<u><em>D) 6y + 1z = 7x - 3w (Equation)</em></u>
