​

Answer 1

Answer:  133

Step-by-step explanation:

Attempt to find the difference betweeen the numbers

7 -3 = 4

17-7 = 10

39-17 = 22

85-39 = 46

Calculate the differences between:  

10-4 = 6 , 22-10 = 12 , 46- 22 = 24         (Notice the pattern!!!!)

Therefore since the difference is being multiplied by 2, your next number's difference will be 48

So 85+ 48 = 133
