Math 10 – Week 16

In this week of math we learned about arithmetic and geometric sequences and series. An arithmetic and geometric sequence is just another form and way of finding equations and slope.

an arithmetic sequence looks like: 3, 6, 9, 12,etc…. you can see that its going up by +3
an geometric sequence looks like: 4, 8, 16, 32, 64,etc…. in this one its getting multiplied by 2 each time

and a arithmetic series is the same as the sequence except its adding the sum of all the numbers: 2 + 4 + 6 + 8 + 10etc…

we learned how to find the equations and make it so that we don’t have to count to keep finding like the 20th number in the pattern.

so in conclusion, arithmetic is a pattern that uses addition or subtraction and geometric is a pattern of sequence that uses multiplication.
