There are two solution: -3 and +2.
They don't necesarily,3 is a triangular number and 10 is a triangular number. Their sum is 13 which is not a square number.They don't necesarily,3 is a triangular number and 10 is a triangular number. Their sum is 13 which is not a square number.They don't necesarily,3 is a triangular number and 10 is a triangular number. Their sum is 13 which is not a square number.They don't necesarily,3 is a triangular number and 10 is a triangular number. Their sum is 13 which is not a square number.
Let 'N' be the number. The sum of the number and 13 is (N+13).The square of the sum of the number and 13 is (N+13)2N2 + 26 N + 169.It's probably easier to add 13 to the number and then square that answer ... less arithmetic.

ok so this is a little hard umm... the 10th prime number is let's see: 1,2,3,5,7,11,13,17,19,23 <------ 23 And the 10th composite number is: 4,6,8,9,10,12,14,15,16,18<------- 18 SO 23 plus 18 ISSSSSS........... 41 So the sum of the 10th prime number and the 10th composite number is 41!!! * * * * * 1 is neither prime nor composite. So the tenth prime is actually 29 and the sum is 47.
sum of the 13th and 14th and 15th prime numbers = 1311st to 12 prime numbers = 2, 3,5,7,11,13,17,19,23,29,31,3713th prime number = 4114th prime number = 4315th prime number = 47=================sum.......................=131
the answer is 162 duh.
