You simply add three consecutive integers (for instance 1,2,3 or 25,26,27) and take the square.
Example: (12+13+14)2 = 392 = 1521.
Or generally: (n + (n+1) + (n+2))2, where n is the first integer.
There is no set of three consecutive whole numbers that add up to 154.
There are no such whole numbers. The sum of three consecutive whole numbers must be a multiple of 3; as 68 is not a multiple of 3 (68 = 3 × 22 2/3) it cannot be the sum of three whole numbers.

The numbers are 30, 31 and 32.
There is no set of three consecutive whole numbers that add up to 154.
The square root of 47 lies between the consecutive whole numbers 6 and 7.

-3, -2 and -1.
9 and 10
The sum of 3 consecutive whole numbers is always equal to 3 times the middle number in that sequence.
Correct!

Yes but the on prime numbers are 2,3
