7 + 8 = 15...............the next two numbers in pi...............................the 1st zero is between 14i and 15i......14 and 15 in pi............just under the dec point.........................add 5 to 15 it is 20..................

Where u truncate stuff at ........matters.............also........why might 20 be imp???......40 - 60...........5 primes............................................there are 4 primes..........in single digits.......just 4.............4 in a one.......ten span....................4 in the next 10 numbers................the 1st series in double digits.....10 - 20...............4 and 4.....................................like how the fraction below looks......................

Two 10s........................like the line at 1/2.......................the 1st two series of 10......both contain 4 primes..........no more, no less........like 14i................4 in ten........and again.....4 in ten........



3.14 / 4 = 0.785
