Each number must be added by preceeding odd number
0+2=2
2+3=5
5+5=10
10+7=17
17+9=26
26+11=37
37+13=50
50+15=65
Therefore 64 is odd
0+2=2
2+3=5
5+5=10
10+7=17
17+9=26
26+11=37
37+13=50
50+15=65
Therefore 64 is odd

Square of the x and add +1, x =1,2,3,4,5,6,7,8.
Square(1)+1=2, square(2)+1=5,.......square(8)+1=65.
So, Result is 64.
Square(1)+1=2, square(2)+1=5,.......square(8)+1=65.
So, Result is 64.

The difference are odd.
5-2=3
10-5=5
17-10=7
26-17=9
37-26=11
50-37=13
But 64-50=14 which is not an odd number.
5-2=3
10-5=5
17-10=7
26-17=9
37-26=11
50-37=13
But 64-50=14 which is not an odd number.

2+3 = 5.
5+5 = 10.
10+7 = 17.
17+9 = 26.
26+11 = 37.
37+13 = 50.
but 50+15 = 65.
Hence, 64 is odd in the series.
5+5 = 10.
10+7 = 17.
17+9 = 26.
26+11 = 37.
37+13 = 50.
but 50+15 = 65.
Hence, 64 is odd in the series.

Difference between each number is odd like 3, 5, 7, 9. And last two numbers difference is even.

5+5=10
10+7=17
17+9=26
26+11=37
