what is the pattern of 2 10 6 7 3 x 10 100 X 5 21 13 x x 15

what is the pattern of:

2 10 6 7 -3 x -10 100 X

5 21 13 x x -15 x x x

it is an array of 2 rows and 9 columns.

pattern is :

2,10,6,7,-3,-8,-10,100,-113

5,21,13,15,-5,-15,-19,201,-225

1) you need to multiply each number from row 1 by 2 then add 1 ( 2x+1=y)

lets take 1^st number in row 1 : x=2 ,y=? put x value in above equation 2*2+1=5

then take y= -15 from row 2 then 2x+1 = -15 so 2x=-16 so x= -8

3) sum of all element in row 1 = sum of all element in row 2
