A sequence is consist with elements and a list of numbers. a series is a list of numbers adding together. There are wo types of sequence and series , arithmetic and geometric. Arithmatic means that the elements are related by addition. Geometeic means that the slements are related by multiplication. Arithmetic formula is An= A1+(n-1)d. A1represents the first term of the series. And d is the difference between two terms. N means the nth term. Geometric formula is An=A1*r^(n-1) A1is the first term and r is the rate of two terms. We can get r by dividing any two terms next to each other. We can write eries into summation formation.
