<p>After the first term, each term in a sequence is 3 greater than 1/3 of the preceding term. If t is the first term of the sequence and t doesn't equal zero, what is the ratio of the second term to the first term?</p>
<p>A) t+9/3</p>
<p>B) t+3/3</p>
<p>C) t+9/3t</p>
<p>D) t+3/3t</p>
<p>E) 9-2t/3</p>
<p>Easiest way is prob plugging in numbers. </p>
<p>If first term is 9
9, 6, 5</p>
<p>Then plug in 9 in every answer choice and see which ones give you 6.
A. 6
B. 4
c. fraction
d. fraction
e. negative? </p>
<p>So A is the only one that gives me 6 so that would be m yanswer. You can check with another numebr if you want too.</p>
<p>NBA Fan is incorrect. The questions asks for the ratio of the second to first.</p>
<p>First term is T
Second term is T/3 + 3 AKA T+9/3 </p>
<p>Ratio of 2nd to first. </p>
<p>T+9/3 / T =<br>
T+9/3T .</p>
<p>C.</p>
<p>Since NBA was nice enough to give us an example, we'll use it.
First number is 9, second is 6 .</p>
<p>6/9 = .666666667</p>
<p>Plug it into the equation and you will get the same ratio.</p>
<p>BigB_85, all your choices are wrong.</p>
<p>why? go figure.</p>
<p>1st : t
2nd : 3+ 1/3t</p>
<p>2nd/1st
this is the algebra way.
but yeah, ur choices are all wrong.
so in this case, =]</p>
<p>Ren.</p>
<p>1/3t+3 translates into t+9 / 3 . Put that over t and you get C.</p>
<p>=)</p>
<p>Yeah I got C as well. This is a pretty straight forward problem.</p>
<p>haha wowwww. i assumed itd be asking for second term in terms of t. i should really read whole question. But yeah for this problem, I would first find out the first 2 terms (9, 6) and then plug in 9 for every choice until I get 2/3.</p>
<p>Ren</p>
<p>The choices are correct. He just left out the parentheses. People need to learn how to do math correctly. Leaving out parentheses kinda changes the answer...</p>
<p>i know that, but i just hated when people give out ambiguous answers, though its obvious...</p>
