In order to find the sixth term b6 of this geometric progression, it is necessary to substitute the value n = 6 into the formula bn = 64.5 * (-2) ^ n, which sets the given geometric sequence and calculate the value of the resulting expression on the right side of this formula:
b6 = 64.5 * (-2) ^ 6 = 64.5 * 2 ^ 6 = 64.5 * 64 = 4128.
Answer: the sixth term of this geometric progression is 4128.
