Which is n/2(2a + (n - 1)d) where a is the first term, d is the difference between the terms and n is how many terms there are.
a = 31
d = 1
n = 29
29/2(62 + 28) = 29 x 45 = 1305
31 + 59 = 90
59 = 47 + 7 + 5, 59 = 41 + 13 + 5, 59 = 31 + 23 + 5, and there are more.
which three prime numbers have a sum of 59
The sum of the prime numbers is: 31+37+41+43+47+53+59 = 311
They are: 31+37+41+43+47+53+59 = 311The sum of all prime numbers between 30 and 60 is 311.
31 37 41 43 47 53 59
17 + 19 + 23 = 59
13 + 17 + 29 = 59
31 + 37 + 41 + 43 + 47 + 53 + 59 + 61 + 67 = 439
They are: 31+37+41+43+47+53+59 = 311The sum of all prime numbers between 30 and 60 is 311.
