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.
83, 3,and 2 are prime numbers which add up to 88.
