Conjecture: the next number in this sequence:
20, 18, 15, 11, 6,
will be 1. is this conjecture true?

yes.
no, it will be 10.
no, it will be 5.
no, it will be 0.
no, it will be 15.

No, it will be 0.

In the sequence each number is subtract 1 more then what was subtracted from the previous number.

20 - 2 = 18

18 - 3 = 15

15 - 4 = 11

11 - 5 = 6

Now, we know that 6 will be subtracted by 6.

6 - 6 = 0

Hope this Helped! Good Luck!
