This week is the second week in math 11. We learned Geometric Sequences and Geometric Series. A Geometric Sequence is a sequence in which the ratio of the common terms is equal and a Geometric Series is a series with a constant ratio between successive terms. For example, the series. Also, we learned how to input code in Edblogs for example, .

# Math 11

# Week 1 – My Arithmetic Sequence

S=+ …..

= 20

Common difference: + 10

What’s the and What’s the

*

Solution:

*

*

*

=+(n-1)d

=20+(250-1)10=2510

*

*

*

=20

=20+20+(10)=50

=20+20+(10)+20+(10)+(10)=90

=20+20+(10)+20+(10)+(10)+20+(10)+(10)+(10)=140

*

*

*

= 20+20+(10)+20+(10)+(10)+20+(10)+(10)+(10)+***

= x (20 + 510)

= x 530

=56250

In conclusion, = 2510 and = 56250
