reply to this like a class mate Arithmetic an geometric sequences both follow a pattern that helps you predict the next number. They each have a rule you can use to find any term in the sequence, which makes them useful for showing growth or change over time. The main difference is how they change. For example, Arithmetic sequences add or subtract the same number each time, while geometric sequences multiply or divide by the same number. That is why Arithmetic patterns grow steadily, and geometric ones grow or shrink faster. A sequence is just an ordered list of numbers, and a series is what you get when you add the numbers together. A series is the sum of the sequence
