Arithmetic sequence is a sequence of numbers such that the difference between the consecutive term is constant
e.g. 5,7,9,11,13,15,17    diff=2

geometric sequence is a sequence of numbers that follows a pattern where the next term is found by multiplying by a constant called the common ratio.
e.g. 2,6,18,54,162    ratio = 3
