Answer:
Code:
range_sum = 0
for x in range(20, 100, 10):
range_sum += x
print(range_sum)
Explanation:
Declare variable (we'll use it to keep track of the sum):
range_sum = 0
Start a loop with the range function (x is the current number, 20, 100 are the numbers to start and stop by and 10 is the number to increase by):
for x in range(20, 100, 10):
Add the current number to the sum and print it:
range_sum += x
print(range_sum)
