hello,

i need some practises on:

1)the language and notation of sequence.

2)Recursive definition for a sequence

3)the Nth therm or general term for a sequence.

can someone please give me some useful website regarding the topics above (or any other possible topics relating to those)? it's for my applicable maths inclass investigation test. i was given a practise/info sheet at school, but i have already finished it and i am worried that the questions in the actual test will be much challenging than the ones that i was given.

thanks
