Explanation:
Just keep adding 7 to the previous number to get your answer.
Or if you want a specific answer for a multiple such as the 51st multiple of 7 you can just do 51 x 7 to get your answer. If you want to find out whether a number is a multiple of a number you can simply divide. An example would be 357 / 7 = 51, so 357 is the 51st multiple of 7.
