Answers
GPT 3.5
To find out which term is 54 in the arithmetic sequence -18, -12, -6, we can find the common difference by subtracting the second term from the first term:
-12 - (-18) = -12 + 18 = 6
This means that the common difference between each term is 6.
Now we can find the position of the term 54 by dividing the difference between it and the first term (-18) by the common difference (6):
(54 - (-18)) / 6 = 72 / 6 = 12
Therefore, the 54th term in the arithmetic sequence is 54.
-12 - (-18) = -12 + 18 = 6
This means that the common difference between each term is 6.
Now we can find the position of the term 54 by dividing the difference between it and the first term (-18) by the common difference (6):
(54 - (-18)) / 6 = 72 / 6 = 12
Therefore, the 54th term in the arithmetic sequence is 54.
