1×5×n
The expression 1×5×n, where n represents any integer, is a simple mathematical formula used to describe numbers that are multiples of 5. This expression can be simplified to 5n. The result of 1×5×n will always be a number that is divisible by 5, meaning it will end in either a 0 or a 5. For instance, if n equals 2, then 1×5×2 equals 10. If n equals 7, then 1×5×7 equals 35. The variable n can be any integer, including positive numbers, negative numbers, and zero. When n is 0, the result is 0. When n is a negative integer, such as -3, the result is -15. The pattern of the resulting numbers will consistently be a sequence of multiples of 5, both positive and negative, with 0 in the center. This type of expression is fundamental in understanding basic number theory and sequences.
