This is how to do the nth term. Read this post, it stays firm. Whaaaaaaaat!!!
Sorry, I felt like rapping :)
Anyway here is an example:
If the nth term is 4n+3, what are the first three terms???
This might sound complicated at first, but it really isn't!!!
'The first three terms' is just a fancy way of saying the first three numbers in a sequence.
For the first term, n=1 , so let's hope you know your algebra!!!
4 X 1= 4+3= 7 because 4n+3 is the nth term <----------- 7 is the first term in the sequence!!!
For the second term, n=2. So:
4 X 2= 8+3= 11 <------------ 11 is the second term in the sequence!!!
And now, the third term, so (You guessed it!!!) n=3 this time!!!
4 X 3= 12+3= 15
So the first three terms are (Drumroll please!!!): 7, 11, 15!!!
You might be asked to find the 100th term, but now you know this, it's easy as ABC, 123, Do Rey Me!!!
So: n= 100, and following the nth term 4n+3:
4 X 100= 400+3= 403!!!
Voila!!! That is the nth term!!!
