<p>For pg. 541 section 7, question 15, why is the answer C and not E?</p>
<p>LOL, how many people even have this book yet? Anyway, I don’t have it but I’ll assume you’re asking about the 2, -4, 8 … question.</p>
<p>Imagine the first 50 terms as 25 pairs of numbers. The first in each pair is positive, the second is negative:</p>
<p>2, -4
8, -16
32, -64
128, -256 etc.</p>
<p>All the negative numbers (25) are less than 100, but only three of the positive numbers are less than 100.</p>
<p>Oops, just realized you’re asking about CR, sorry 
I’ll leave this up for some other person.</p>
<p>^ 
lol, thanks for trying though. I appreciate it.</p>
