today we learned about sequences
sequences are very exciting and fun to do
there are 2 different kinds of sequences
arithmatic sequences are found by adding or subtracting a common number ex: 2,4,6,8
geometric sequences are found by multiplying a common ratio
ex: 2,4,8,16
a recursive formula is based on the preceding term
the formula is tn=tn-1x2
nMin=1st term
u(n)=formula
u(mim)=value of first term
