Well, it depends whether when I do this I want to say this is 2, 4,8, 16

这个看情况而定我想把他们写成怎样
or whether I want to call it 1,2, 4, 8, 16.

2 4 8 16或者是1 2 4 8 16
So I don't know which is the right thing.

我不知道哪一个更恰当
Probably I should have done 1,2, 4,8.

可能我写成1 2 4 8更好
Probably the way I have it here which is t - 1.

可能这里应该是t-1
