1) -4d + 3 if d=-1
2)k-m if k=4 and m=-10
3)t/w if t= 6 and w= 3
4)x2 + y2 if x= 7 and y= 5

1) -4d + 3 id d = -1

(-4 * -1) + 3 = 4 + 3 = 7

2) K - m if k = 4 and m = -10

4 - ( -10 ) = 4 + 10 = 14

3) T / w if T = 6 and w = 3

6/3 = 2

4) X2 + y2 if x = 7 and y = 5

(7)2 + (5)2 = 49 + 25 = 74

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
