Answer 1

Answer:

Jay could be thinking of 11  

Step-by-step explanation:

Prime numbers are the numbers that have two factors only, 1 and itself as

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, .................

All prime numbers can divide by 1 and itself only

∵ A number is a prime number

∵ The sum of its digits is 1 more a square number

∴ The sum of its digits = 1 + x, where x is a square number

→ We will start with the first prime number of 2-digits

∵ 11 is a prime number

∵ The sum of its digits = 1 + 1 = 2

→ Substitute it in the equation above to find x

∴ 2 = 1 + x

→ Subtract 1 from both sides

∵ 2 - 1 = 1 - 1 + x

∴ 1 = x

∵ 1 is the square of 1

∴ Jay could be thinking of 11
