The term that is 54 in the automatic sequence -18, -12, -6 is the 10th term. Each term is increasing by 6, so to find the 10th term, you would add 6 to the previous term 9 times:
-6 + 6 = 0
0 + 6 = 6
6 + 6 = 12
12 + 6 = 18
18 + 6 = 24
24 + 6 = 30
30 + 6 = 36
36 + 6 = 42
42 + 6 = 48
48 + 6 = 54
Therefore, the 10th term in the sequence is 54.
