Option c) The answer displayed by the algorithm for any known value of n can always be predicted.
The following algorithm which uses an integer variable n.
Explanation:
one integers must be entered by the user.
Example:
n=2
double the value of n.
n=2*2
=4
add 34 to the answer
34+4=38
Round the answer to the nearest ten
=38(rounded nearest 10)
=40
Sum the digits of the answer
=4+0
=4
Display the final answer
=4
Hence, The answer displayed by the algorithm for any known value of n can always be predicted.
