Part 1: Determine the geometric partial sum the sum of 3 times 2 to the I minus 1 power from 1 to 7. (2 points)

Part 2: In complete sentences, explain the necessary steps required to find the partial sum. Include an explanation of whether this partial sum is divergent or convergent in nature.
only need help on last sentence, i already know the partial sum is 381.
