The nth term
Posted: Tue May 20, 2014 12:52 pm
Hi,
I downloaded some 11plus maths papers from a website and it stated are suitable for 11plus CEM exams. (we are Bucks)
One of the qs we came acrsoss was the "nth term and next in sequence" it took a bit of working out before we got the hang of it, prior to looking at the answer.
Question
Graham creates a sequence with the nth term 3n2+1
What are the first two terms in the sequence.
A) 1,3 B) 4,13 C) 7,13 D) 10,37 E) 4,7
I haven't come across this in the other maths books we have been working on...has anyone come across this for the 11 plus....or what is likelihood of this topic coming up for Bucks CEM exam?
