Is there a pattern behind prime numbers? |
|
Answer» A clear rule determines exactly what makes a prime: it's a whole NUMBER that can't be exactly divided by ANYTHING except 1 and itself. But there's no discernable pattern in the OCCURRENCE of the primes. ... That's because after the number 5, there are only four possibilities — 1, 3, 7 and 9 — for prime last DIGITS. |
