Answer:
C
Step-by-step explanation:
The very first term would result in 2 having an exponent in 0 making the equation -3 * 1 which is just -3 and C is the only option.
To further prove this -3 * 2^3 is -24. n is the term that you are looking for. So finding the fourth term would mean you would take 4-1 which is 3 thus making the exponent 3.
