Given: 3 perfect square numbers x, y and z
To find: The smallest possible value of x?
Solution:
- Now we have given three numbers by following condition:
x > y > z > 0
and these numbers are in AP.
- Now lets write all the perfect squares from 1 to 10, they are:
1, 4, 9, 16, 25, 36, 49, 64, 81, 100
- Now from this, we can see that 25 is half the sum of 1 and 49.
- So the numbers could be 1, 25 and 49
- Let x = 49, z = 1 then:
x + z / 2 = y
49 + 1 / 2 = y
y = 50 / 2
y = 25
- So the value of y is 25 and x is 49.
Answer:
Hence, the smallest possible value of x is 49.
