Question

Help me to arrange the numbers from 1 to 15 in a row such that the

sum of any two adjacent numbers is a perfect square​

Answer 1

Answer:

1, 2, 3,

Step-by-step explanation:

1*1=1

2*2=4

3*3=9

when we write 4*4=16 we get 16 that is no correct because 16 is above 15

Answer 2

answer:

9,7, 2, 14, 11, 5, 4, 12, 13, 3, 6, 10, 15, 1, 8

explanation:

sum of 9&7 is 16 which is square of 4

sum of 7&2 is 9 which is square of 3

similarly sum of 2& 14 is 16 which is square of 4

and goes on..

thus the sum of any two adjacent numbers is perfect square as required.
