Math Problem Solution

<p>Okay, this is a #5 Math problem...I figured out how to solve it, but I did it the long way...which = waste of time. Can someone show me a shortcut to solving this problem. Here it goes:</p>

<p>8, 17, 26, 35, 44, ... </p>

<p>"The first 5 terms in a sequence are shown above. Each term after the first is found by adding 9 to the term immediately preceding it. Which term in this sequence is equal to 8 + (26-1)9?"</p>

<p>A) 8th
B) 9th
C) 25th
D) 26th
E) 27th</p>

<p>I eliminated A and B off the bath because 8 + (26-1)9 = 233. Thanks</p>

<p>Well, each step is increasing by 9(n-1)+8.
for example: The 2nd term would be 9 (2-1) + 8. </p>

<p>So if its (26-1) it must be the 26th term.</p>

<p>you are lucky it wasn't asking the 20394th term, using parihs's method... that'll take hours</p>
