129
A sum is used to compare two or more numbers - a single number cannot have a sum.
The sum of all prime numbers less than 30 is 129.
You can tell a number is divisible by 3 when the sum of its digits is equal to 3 or a multiple of three. In this instance, 1 + 2 + 9 = 12/3 = 4, therefore 129 is divisible by 3.
It is 42 because 42+43+44 = 129
