Asequence can be described using the rule an = –2 + 3(n-1). which is the
value of the 20th term in this sequence?

The 20th term of the arithmetic sequence is 55

Step-by-step explanation:

A sequence can be described using the rule:

an = –2 + 3(n-1)

Where

an is the value of the nth term of the arithmetic sequence.

- 2 is the first term of term of the sequence.

n is the number of terms in the sequence.

To determine the 20th term, we will substitute n = 20 into the equation. It becomes

a20 = - 2 + 3(20 - 1)

a20 = - 2 + 3×19

a20 = -2 + 57 = 55

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
