Hi Pratap,
I wanted to explain this answer but Sree hasn't posted his answer. I think he might have forgot it. When he does and if I am correct, I will then explain my answer to this question. Hey, Sree please post the answer to this question. I am still waiting for the answer and an explanation of the answer from you.

Answer is
79
these are 'happy numbers' ie numbers, square of whose digits when added successively finally reduces to digit 1. go on squaring till you get a single number.
eg number 7 : 7^2 = 49 > 4^2 + 9^2 = 97 > 9^2 + 7^2 = 130 > 1^2 + 3^2 + 0^2 = 10 > 1^2 + 0^2 = 1
