Display it as output using for loop.

Answer 1

# Python solution below

for j in range(3):
for i in range(5):
print(i*(j+1)+1,'\t\t', end='')
print()

# Nested 'for i' loop iterates five times and is itself iterated three times. Each time of all the fifteen routines the calculation is done and printed.
