LO: know special sequences

Here are the first few square numbers, triangle numbers and Fibonacci numbers


For the Fibonacci numbers you add 2 consecutive numbers to get the next one, so 1+1=2, then 1+2=3, 2+3=5 etc so to get the next one in the pattern you need to do 13+21

Copy the sequences and try to continue each one to the 15th term (answers below - check yours!)

Now use your answers to try a few questions from Ex 2E qu 2, 4 then Qu 7a,b,c,d

Check those then do Ex2F Qu 2 and 3
