arithmetic recursive formula

a_{n} =a_{n-1 }times r

geometric recursive formula

g_{n}= g_{n-1} times r

arithmetic explicit formula

a_{n}=a_{1}+d(n-1)

geometric explicit formula

g_{n}=g_{n} times r^{n-1}

what is r is sequence equations?

r is common ratio or difference. how much the sequence changes

what is n in a sequence equation?

n is the number or the term

what is a or g in a sequence equation?

The first term of the sequence

when rounding to nearest whole number what do you change if theres a decimal?

If the decimal is over 5 you go up one if its under 5 you just take it away

what is the domain of a sequence?

positive or neg #'s

when do you use a closed circle on the number line?

when the number is less /greater then or **equal** to
then x

when do you use a open circle on the number line?

when the number is less or greater then x

how do you describe a graph?

write if its increasing and or decreasing what type of function its shape if its discrete or continuous

what is a discrete graph?

each input only has on output is a function and points **are
not** connected

what is a continuous graph?

starts at one specific point points are connected (if its not discrete )

what is correlation

relationship or connection between two or more things

what is causlation

the action of causing something

when do you keep awnser as a simplified fraction?

when the answer has a decimal in y int. or compound inequality problems.

when do you use or?

when "paths" are going opposite ways and don't overlap.

when do you use and?

when there's a line between both points connecting them or they overlap.

when do you flip sign around?

when dividing by a neg #

whats the easiest way to find y int?

ignore x then solve

what is no solution?

no x false statment

what is one solution

x = #

what is infinite solution

x goes away true statement
