<p>Heh. When it’s a large number, which normally cannot displayed by your calculator, it’s usually a problem like this in which you find patterns by just looking at the end numbers.</p>
<p>I always get it mixed up because I always think that if it has no remainders, it should start on the first term since I consider having no remainder yields a new sequence of numbers (i try to make sense, but I dont think I did)</p>
<p>I just thought of it differently after completing your problem. Just think that if it has no remainder, it’s a remainder of, in your case, 4 (even though it’s the divisor, but just think it that way) so it’s the last number in the sequence.</p>
<p>For the stat problem, I encountered almost the exact same on on the DEC SAT except it was around 10 to 40 range. I wasn’t thinking straight that day so I wrote out all the numbers and counted in pairs. I realized that averaging would do the trick since they were consecutive. </p>
<p>I recommend studying for the SAT II math level 2 like someone else recommended, it would help a ton with the basics.</p>
