Answer:

B. No

Explanation:

The formula of a number pattern with a common difference is Tn= a +d(n-1), where a is the first term and d is the common difference.

Notice that the numbers decrease by 4 from the previous term. Hence the common difference is -4 in this case.

Tn= 22 -4(n-1)

Tn= 22 -4n +4

Tn= 26 -4n

Let's check to see if the formula is right.

When n=2,

T2= 26 -4(2)

T2= 18

This is correct as the 2nd term in the sequence is 18.

If the number is in the sequence, n would be a whole number since nth term cannot be a fraction/ decimal etc.

When Tn= -204,

-204= 26 -4n

4n= 204 +26

4n= 230

n= 230 ÷4

n= 57.5

Since n is not a whole number, -204 is not in the sequence.
