Sequences & Series2 Determine how many primes there are in the ranges 1 1000 1001 2000 and so on up to 9001 10000 Can you see why the Greeks might have wondered if they would run out Hint there are a number of websites that have lists of prime numbers Even easier use the Mathematica command Prime Pi k which gives the number of primes less than or equal to k
