Studt the list of numbers and use it’s pattern to predict the next three numbers describe the pattern

If you find the difference between the numbers you'll see that if you add 2, 4, 8, 16,... you'll get that sequence!

E. g.
1 + 2 = 3
3 + 4 = 7
7 + 8 = 15

So I'll predict that to gt the next nunber, you'll need to add this to current number:


Where n is just the position of the current number (1st, 2nd, 3rd). So the number after 31 should be:



And the number after 63 should be:



Now you try the last one! You can comment the answer and I'll check if it's right.
