MAGIC SQUARE 3X3 SUM=24

By
 MAGIC SQUARE 3X3 SUM=24:
In a magic square 3x3, if we take numbers from 1 to 9 then the magic sum equal to 15. The magic square is as follows:
4
9
2
 3
5
7
8
1
6
In the above magic square 3x3 magic sum is 15. In the above magic square 3x3 we are used numbers from1 to 9 arranged in 9 boxes. In any direction the sum equal to 15.
Row wise  4+9+2=15, 3+5+7=15, 8+1+6=15.
Column wise 4+3+8=15, 9+5+1=15, 2+7+6=15.
Diagnol wise: 4+5+6=15, 2+5+8=15.
The above magic square also can be written as follows:
5-1
5+4
5-3
 5-2
5
5+2
5+3
5-4
5+1
In the above figure , shows the relation between middle number and other numbers. In the magic square we are taken numbers from 1 to 9 and number 5 is between 1 to 9.
If we write  x in place of 5 in above magic square.                                        
X-1
X+4
X-3
 X-2
X
X+2
X+3
X-4
X+1

Now we will write different magic square’s with different magic sum’s

MAGIC SUM=24. NUMBERS: 4,5,6,7,8,9,10,11,12  MIDDLE NUMBER: 8
       
8-1
8+4
8-3
8-2
8
8+2
8+3
8-4
8+1
Result of above magic square:
7
12

Average of first n even numbers

By
Even numbers are 2,4,6,8,10,…. Average = sum of elements/ no of elments Now we will see the sum of elements: Sum of first 2 even numbers: 2+4= 6= 2(2+1) Sum of first 3 even numbers: 2+4+6= 12= 3(3+1) Sum of first 4 even  numbers: 2+4+6+8=20= 4(4+1) Sum of first 5 even numbers: 2+4+6+8+10 = 30 = 5(5+1) Sum of first n even numbers: 2+4+6+8+10+. . . . .  n numbers= n(n+1) Now we will see average: Average of first 2 even numbers= (2+4)/2                                                           = 6/2                              ...
