Answer 2

if we see the pattern, it is squares of number like
100= square of 10
81= square of 9
64= square of 8
49= square of 7
so if we continue, then square of 6= 36
                             square of 5= 25
                             square of 4= 16
                             square of 3= 9
                             square of 2=4
                          and square of 1= 1
so the pattern will be= 100, 81, 64, 46, 36, 25.....
