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.

Well, darling, the average of 51, 52, and 56 is 53. That's right, just add them all up and divide by how many numbers you have. In this case, it's as easy as pie.
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.
