Several groups of 3 numbers add up to 51
Here are some:
30 + 20 + 1 = 51
15 + 30 + 6 = 51

Actually, there are an infinite number of possibilities.
Here are a few more.
16 + 17 + 18
16.9 + 17 + 17.1
16.00009 + 17 + 17.99991
0.1 + 0.2 + 50.7
etc.

12, 16 and 23 is one possible triplet.

Odd numbers always add up to be even numbers EX: 1+1=2 5+3=8 101+51=152 7+3=10 (Got the point)

The digits in 51 add up to 6, so it is divisible by 3.51/3 = 17 (17, like 3 is a prime number)so the prime factors of 51 are the two numbers, 3 and 17(51, like all numbers, can also be divided without remainder by 1, but this is not usually counted as a prime factor)
To get the (mean) average, add them up and divide by 3 [since there are 3 numbers]: 12 + 16 + 23 = 51, and 51 ÷ 3 = 17.

Oh, dude, you just add them up and divide by how many numbers there are. So, like, 51 + 52 + 56 = 159, and since there are three numbers, you divide 159 by 3 and get 53. So, the average is 53.
First find the number which is 1/3 of 51. This is 17. Thus any three numbers which average 17 will always add up to 51. For the numbers to be consecutive and have an average of 17, the middle number must be 17 and the two remaining numbers are 17-1 and 17+1 ie 16 and 18. So the three consecutive numbers are 16, 17 and 18.
83, 3,and 2 are prime numbers which add up to 88.
