Taylor"s 12(I think) Blog

This is some of my notes from Ch. 13.1.

A sequence is a set of numbers. Today we will learn a bit about arithmetic sequence which is when you add the same number to every term.

This is the formula:

tn= t1 +(n-1)d

d is the number that is being added or subtracted. The n and one by the t are small to.

Ok let's do some examples.

Find the first 5 terms of this equation tn+ 6n+2

t1= 6(1)+2 First replace n with 1,2,3, and for and solve the equation.
t2=6(2)+2
t3=6(3)+2
t4=6(4)+2

t1= 8 Then you have your answers.
t2= 14
t3= 20
t4= 26

8,13,18,23.... find the formula for the nth term.

8,13,18,23.... First you need to figure out what is being added or subtracted from

each number. In this case it is adding 5.

tn=t1+(n-1)d Then write out your equation.

tn=8+(n-1)5 Then fill out the parts that you know2.

tn=8+5n-5 Then multiply 5 times n and -1.

tn= 3+ 5n Then you just add up your like terms and this is your answer.

These are some of my notes on Ch. 13.1. So UN TIL SCHOOL STARTS SEE YALL!!!
