this week we did not really get to do anything. because of the sat and the field trip and then thing with mu alpha theta. so we mainly did aleks the whole week. Which most of them i did not know what i am doing so i get put out or i fail my assestment and have to do the same things over and over. okay so i am going to back to chapter 13 section 1. In this chapter they are talking about sequences. A sequences is a set of number. There are two different type of sequences we learn about in this section, arithmetic and geometric. I am only talking about arithmetic because i am sleeping and ready to go to bed lol :) Arithmetic squence is when you add the same number to every term. The only formula you need to know for this problem is tn=t1+(n-1)d. d is the number that you are adding to each term. Example Problem Find the first four terms of this equation 7n+2. in the problem you always replace n with number term you are on. t1=7(1)+2=9 t2=7(2)+2=16 t3=7(3)+2=23 t4=7(4)+2=30 So the first four terms in this equation is 9,16,23,30
