Finding Missing Terms in Geometric Sequence Ex #1

# data[].attributes.body
-Recursive:used to find the next term from the previous term
f(n)=f(n-1)x change
-Summation Notation:used to find the sum of a sequence

# data[].attributes.body
*write an arithmetic or geometric sequence in explicit form or recursive form; create a table and graph
*write a sequence's sum in summation notation and find the sum with the formula
*find missing numbers in an arithmetic/geometric sequence with arithmetic/geometric means
-- create an equation with the missing number of steps to get the next term (Ax) and solve
*Identify if linear, exponential or neither
*Model linear or exponential functions with explicit equations to answer questions from the equation
*Find the average rate of change
*Identify Concavity

Geometric Sequence: multiply by a common ratio each term
Arithmetic: add by a common difference each term
Recursive: allows one to look at the next term from the previous term
Explicit: equations that allows one to look at any term
Discrete: Do not connect the dots on a graph . Pattern happens only at specific moments
Continuous: dots are connected on a graph. Pattern happens constantly overtime
*Compound Interest (increasing)
A=P(1+r)^t
*Decreasing Interest
A=P(1-r)^t
P= Principal (initial amount)
r=interest rate (3%=0.03)
t=Time
