## 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.

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:

${\displaystyle 3^{2}+4^{2}=5^{2}}$
${\displaystyle 3^{3}+4^{3}+5^{3}=6^{3}}$
${\displaystyle 3^{4}+4^{4}+5^{4}+6^{4}=7^{4}-143}$.
