false none of the numbers add up to 31
They are 29, 30 and 31.
64
31, 32, and 33 add up to 96.
91+31+151=273
2, 7 and 31 add up to 40.
If you can only add some or all of the numbers together - you cannot achieve a total of 31. You can get the total 31 by the following... (19-2) + 17 - 3
For three prime numbers to add up to 100, one of the numbers has to be 2, because otherwise the three prime numbers would all be odd, which would mean the sum of the numbers would also be odd.Two sets of three prime numbers that add up to 100 are:2 + 79 + 19 = 1002 + 67 + 31 = 100In this case, 67 exceeds 31 by 36, therefore, the three prime numbers in question are 2, 31, 67.
There is no set of three consecutive whole numbers that add up to 154.
{ 2, 19, 79 } { 2, 31, 67 } { 2, 37, 61 }
31, 7 and 5 No justification needed.
