Use the explicit formula an=4−3n to find the seventh term of the arithmetic sequence.

Answer 1

To find the seventh term of the arithmetic sequence using the explicit formula, we substitute n = 7 into the formula an = 4 - 3n:

a7 = 4 - 3 * 7
= 4 - 21
= -17

Therefore, the seventh term of the arithmetic sequence is -17.
