Answer:
The program in Python is as follows:
numbers = [10,20,30,40,50,60,100]
total = 0
for i in range(len(numbers)):
if i != 3:
total+=numbers[i]
print(total)
Explanation:
This initializes the list
numbers = [10,20,30,40,50,60,100]
Set total to 0
total = 0
This iterates through numbers
for i in range(len(numbers)):
This ensures that the index 3, are not added
<em> if i != 3:</em>
<em> total+=numbers[i]</em>
Print the calculated sum
print(total)
