147 has factors other than 1 and itself, so it is not a prime number. For example, 147 is divisible by 3. (You can quickly check this by adding up the digits of 147: 1 + 4 + 7 = 12. If the sum of the digits is divisible by 3, so is the number.) Therefore, 147 is a composite number.
The sum of 3 plus 4 is 7.
147 / 3 = 49 49 will be the center number, just add and subtract 2 to/from 49 and you get 47+ 49 + 51 = 147
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
The sum is 1511.
