Question

Rule: Start at ? Subtract 6 then multiply by 2 each time
? 22- 32- 52 ​

Answer 1

Explanation:

let the number be x

So,

(x - 6) × 2 = 22

2x - 12 = 22

2x = 34

x = 17

Thus, the answer is 17

Answer 2

? = 17
17-6 is 11, and 11 multiplied by 2 is 22.
You can find this out by first dividing the number by 2 and adding 7
