Analyze the explicit formula of the arithmetic sequence an=3.7+12n and report the ninth term, rounded to the nearest tenth.
The explicit formula for the arithmetic sequence given is an = 3.7 + 12n, where n is the term number.
To find the ninth term (n=9), we substitute n=9 into the formula:
a9 = 3.7 + 12(9)
a9 = 3.7 + 108
a9 = 111.7
Therefore, the ninth term of the arithmetic sequence is 111.7 (rounded to the nearest tenth).
