Answer:

Step-by-step explanation:
Given
See attachment
Required
Vertical length / Horizontal length
From the attachment, we have:
--- the vertical length of the larger triangle
and
--- the horizontal length of the larger triangle
So, the ratio is:



Divide by 2

Translation (x,y) ⇒ (x-2, y-16) means the triangle PQR is translated two units to the left and sixteen units down.
Each x-vertices will move two units left and y-vertices will move 16 units down
P(-2, 6) ⇒ (-2-2, 6-16) ⇒ (-4, -10)
Hence y-coordinate of the image of P is -10
9, 9(2)=18, 9(3)=27, 9(4)=36 9(5)=45
9,18,27,36,45……..144
Not sure if this is what you are looking for. If the number of blanks is the amount of numbers allowed then the above will not work
9(13)=117, 9(14)=126, 9(15)= 135, 144
If you can only have 3 blanks then the second one could work.
Again, not sure if this is what you need. But hopefully it helps.
