Look at the next three lines -3,9,-27,81... 1,-3,9,-27... -2,10,-26,82... Let x, y and Z be the number of rows 1, 2 and 3 respectively, and find the value of X + 6y + Z. what is the relationship between the number of rows 2, 3 and the number of rows 1

Look at the next three lines -3,9,-27,81... 1,-3,9,-27... -2,10,-26,82... Let x, y and Z be the number of rows 1, 2 and 3 respectively, and find the value of X + 6y + Z. what is the relationship between the number of rows 2, 3 and the number of rows 1

Line 2 is obtained by dividing each number in line 1 by (- 3)
Line 3 is obtained by adding 1 to each number in line 1
So line 2 * (- 3) = Line 1 = line 3 (- 1)
And X, y, Z are the number of 2012 in each row
Then 6y = 6 / (- 3) * x = - 2x
z=x+1
∴x+6y+z=x-2x+x+1=1
