Using the explicit formula An=28.5+(n−1)4.5%0D%0A%0D%0A%0D%0A=%0D%0A28.5%0D%0A+%0D%0A(%0D%0A%0D%0A−%0D%0A1%0D%0A)%0D%0A4.5%0D%0A, which of the following is the 14th term of the described arithmetic sequence?
To find the 14th term of the arithmetic sequence, we substitute n = 14 into the explicit formula:
A14 = 28.5 + (14 - 1) * 4.5
Simplifying:
A14 = 28.5 + 13 * 4.5
A14 = 28.5 + 58.5
A14 = 87
Therefore, the 14th term of the arithmetic sequence is 87.
