This week in Advanced Math we are learning chapter 13 section 1. This chapter is extremely easy for me I think because you are just finding the next numbers in a or telling how many are in a sequence. Somewhere in that range. There are many different types of problems that you may run into when doing this section but since we have such a good math teacher she has showed us every kind there is that we need to know, well that is for our homework at least.. no telling what we will see on the test. :) Anyways here are the formulas and following the formulas will be some examples which are really easy to catch on to.
Formulas:
arithemetic: tn=t1+(n-1)d
geometric: tn=t1xr^n-1
Examples:
1. Tell weather each set of sequences is geometric, arithmetic, or neither.
a. 3,6,9,12,15...
aritmetic d=3
b. 4,12,16, 20...
geometric r=4
c. 11, 15, 16, 19...
neither
