143 (one hundred forty-three) is the natural number following 142 and preceding 144.
In mathematics
143 is:
- the sum of seven consecutive primes (11 + 13 + 17 + 19 + 23 + 29 + 31). But this number is never the sum of an integer and its base 10 digits, making it a self number. It is also the product of a twin prime pair (11 × 13).
- the difference in the first exception to the pattern shown below:
