The sum of three consecutive multiples of 6 is 666, the multiples are 216, 222 and 228.
3x^2 + 6
It is: 6+12+18 = 36
yes always this is true' example 1,2,3 sum is 6 and is divisible by 3
3(p + 6) or 3p + 18
The sum of three times a number and its square is 10 more than 6 times a number?
6, 7, 8
2, 6 and 12.
There are 216 permutations of three standard dice. Of these, there are exactly 10 that sum to 15, namely 3-3-6, 4-5-6, 4-6-5, 5-4-6, 5-5-5, 5-6-4, 6-3-6, 6-4-5, 6-5-4, and 6-6-3. The probability, then, of rolling a sum of 15 with three standard dice is 10 in 216, or 5 in 108, or about 0.04630.
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
How about 6, 12 and 20?
