1. Look for a pattern in the first three equations. Then, fill in the missing numbers in the rest of the series of equations.
1= 1.22
1 + 2 = 2
nico
1 + 2 + 3 = 3.42
1 + 2 + 3 + ? = ?-?
1 + 2 + 3 + ? +?=?
?.??

1=1 times 2/2 1 + 2=2 times 3/2 1 +2+3=3 times 4/2 1+2+3+4=4 times 5/2 1+2+3+4+5=5 times 6/2

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

the image of (6, 9) under a dilation is (4, 6). the scale factor is
