<u>Given</u><u> </u><u>that</u><u>:</u><u>-</u>
→ 1 sandwich = 2 slices of bread. 
→ 1 hiker = 1 sandwich. 
→ Then we have to find number of bread slices for n hikers .
→ Number of bread slices for 1 hiker = 2 
→ Number of bread slices for 2 hikers = 2 × 2 
→ For 3 hikers = 3 × 2 
So in similar way 
→ Number of bread slices for n hikers = 2×n → 2n 
So <u>2</u><u>n</u><u> </u> is the answer.
