Answer:
In Python
for i in range(-13,0,6):
print(i)
Explanation:
Required: A program to display the given output
From the program, we observe the following:
The output begins at 13 i.e begin = 13
The output ends at -1 i.e end = 1
And the difference between each output is 6.
i.e. 
So, the syntax of the for loop is: (begin, end + 1, difference)
The program explanation goes thus:
<em>This iterates through the -13 to 1 with a difference of 6</em>
for i in range(-13,0,6):
<em>This prints the required output</em>
print(i)
