New cards
Arithmatic sequence
Common difference (slope) change y over change x
Linear- don’t connect dots
An=Ao + dn
An= Ak + d(n-k)
2
New cards
Geometric sequence
Common ratio- constant proportional change (divide or plug in points to find r)
Exponential function- not continuous (don’t connect dots)
Gn= Go r^n
Gn= Gk r^(n-k)
3
New cards
Linear function
Over equal length input value intervals the output values change at constant rate (AROC its equal)
connect dots (arithmatic you don’t connect dots)
4
New cards
Exponential function
f(x)=ab^x
Over equal-length input value intervals the output values change proportionately
The change (b) is multiplication
(Connect dots- while geometric the dots arnt connected)
