[edit] In mathematics

143 is the sum of three consecutive primes (43 + 47 + 53), as well as 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.

Every positive integer is the sum of at most 143 seventh powers (see Waring's problem).

143 is the difference in the first exception to the pattern shown below:

3² + 4² = 5²

3³ + 4³ + 5³ = 6³

3⁴ + 4⁴ + 5⁴ + 6⁴ = 7⁴ − 143
