Question 698320: 14,17,20,23,26
Which equation describes the n^th term of the sequence?
A.f(n)=3+11n
B.f(n)11+3n
C.f(n)=14+17n
D.f(n)+17-3n
Can you please explain how you get the answer? thankyou sooo much, i forgot everything during winter break.

You can put this solution on YOUR website! since the sequence increases by 3 each time that tells you it's a 3n type of sequence. that's the easy bit.
to get the rest of the sequence.....
a plain old 3n sequence goes 3, 6, 9, 12, 15, ..., (like the 3 times table!)
all the numbers in your sequence (14, 17, 20, ...) are 11 above a plain 3n sequence. that is +11
so the sequence is B. f(n)=11 + 3n
