Answer:
Step-by-step explanation:
The code that would best accomplish this task using a while loop would be the following:
list1 = [8, 3, 4, 5, 6, 7, 9]
accum = 0
n = 0
while n < 7:
accum += list1[n]
n += 1
This code will continue throughout the list1 array and add every value to the accum variable.
