Answer 1

Answer:

18. Number of rows = n

Number of rows = nn is a variable that can take any value 1, 2, 3, 4,...

Number of rows = nn is a variable that can take any value 1, 2, 3, 4,...Number of cadets in a row = 5

Number of rows = nn is a variable that can take any value 1, 2, 3, 4,...Number of cadets in a row = 5Thus,total number of cadets is given by the rule = 5 × number of rows= 5n
