To find the seventh term of the arithmetic sequence using the explicit formula an=4−3n, we substitute n = 7 into the formula:
a7 = 4 - 3(7)
a7 = 4 - 21
a7 = -17
Therefore, the seventh term of the arithmetic sequence is -17.
Use the explicit formula an=4−3n to find the seventh term of the arithmetic sequence
