Question 795220
<pre><font face = "arial" size = 4>
I6, 06, 68, 88, ?, 98

We turn that upside-down

86 '¿ '88 '89 '90 '9I

Then obviously we can tell that ¿ is to be replaced by 87

86 '87 '88 '89 '90 '9I

Then we turn it back right-side up again, and we have:

I6, 06, 68, 88, <i>L</i>8, 98

Answer: <i>L</i>8   <font face = "wingdings" size = 6>J</font>
