Answer 1

$\texttt{\textsf{\large{\underline{Solution}:}}}$

The given problem is solved using language - Python.

1. Using loops.

s = 0

for _ in range(21,30 + 1):

   s += _

print('Sum of numbers from 21 to 30 is:', s)

2. By creating a list.

s = sum(list(range(21,30 + 1)))

print('Sum of numbers from 21 to 30 is:', s)

$\texttt{\textsf{\large{\underline{Logic}:}}}$

• Iterate a loop in the range 21 to 30 (I wrote 31 because last value is excluded).
• Add each numbers present in this range.
• Store the sum in variable 'sum'.
• Display the value of the variable 'sum'.
