Some one already told this method above, & is a short cut,
25*5 --> 5^2 * 5.
16*5 --> 4^2 * 5.
9*5 --> 3^2 * 5.
4*5 --> 2^2 * 5.
1*5 --> 1^2 * 5 (answer).
Remaining methods are boring to me.

10^2 + 5^2 = 125.
8^2 + 4^2 = 80.
6^2 + 3^2 = 45.
4^2 + 2^2 = 20.
2^2 + 1^2 = 5.
8^2 + 4^2 = 80.
6^2 + 3^2 = 45.
4^2 + 2^2 = 20.
2^2 + 1^2 = 5.

125 - 80 = 45,
80 - 45 = 35,
45 - 20 = 25.
So the next difference should be of 15.
20-15 = 5 answer.
80 - 45 = 35,
45 - 20 = 25.
So the next difference should be of 15.
20-15 = 5 answer.

According to me,
It's;
125-45 = 80
80-35 = 45
45-25 = 20
20-15 = 5.
So, 5 is the answer.

80-125=-45=-5(5+4),
45-80=-35=-5(5+4-2),
20-45=-25=-5(5+4-4),
x-20 =-5(5+4-6)=-15,
x = 5.
45-80=-35=-5(5+4-2),
20-45=-25=-5(5+4-4),
x-20 =-5(5+4-6)=-15,
x = 5.

@All.
We can do this,
5*25 = 125,
4*20 = 80,
3*15 = 45,
2*10 = 20.
Therefore , 1*5 = 5 ans.
