<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
The three-digit positive integers divided by 7 leave a remainder of 5.
14x7 = 98
98 + 5 = 103
The arithmetic sequence
103,110,117,124,......992,999
l = a + (n - 1)d
999 = 103 + (n - 1)7
n = 129
Thus, the number of 3-digit positive integers is 129 if divided by 7 leaving a remainder of 5.
