[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
[edit] In Internet slang
Also, 143 is commonly seen as the meaning "I Love You" in internet slang. 1, 4 and 3 are the letter counts of those words.[1]
