Answer: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
