Responses
an=0.5×(−6)n−1
A sub n is equal to 0 point 5 times negative 6 raised to the n minus 1 power
an=−6×(0.5)n−1
A sub n is equal to negative 6 times 0 point 5 raised to the n minus 1 power
an=−6×(−0.5)n−1
A sub n is equal to negative 6 times negative 0 point 5 raised to the n minus 1 power
an=−0.5×(−6)n−1
