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:

$3^2%2B4^2=5^2$

$3^3%2B4^3%2B5^3=6^3$

$3^4%2B4^4%2B5^4%2B6^4=7^4-143$
