What is the pattern for -5, 10, -15, 20, -25

The number 5  multiplied by -1 then by 2 then by -3 then by 4 (alternating positive and negative

Step-by-step explanation:

5*-1 = -5

5*2 = 10

5*-3= -15  

5*4= 20    

5*-5 = -25

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
