Arithmetic formula: \[ t_n = t_1 + (n  1)d \] \[t_n \] is the nth term, \[t_1 \] is the first term, and d is the common difference

Geometric formula: \[ t_n = t_1 . r^(n  1) \] \[t_n \] is the nth term, \[t_1 \] is the first term, and r is the common ratio.

Arithmetic sequences have a constant difference between terms: 1, 3, 5, 7,... The difference between successive terms is 2. The general formula for the nth term is a(n) = a(1) + d·(n1) where a(1) = the initial term , d = difference between terms. So to find the 5th term (which we can see in the sequence should be 9), we plug in n = 5 a(5) = 1 + 2·(51) = 1+2·4 = 9 WHEREAS Geometric sequences have a constant ratio between terms: 2, 6, 18, 54, ... The ratio between successive terms is 3. The general formula for the nth term is a(n) = a(1)·r^(n1), where a(1) is the first term and r is the ratio. So to find the 5th term (which we can see in the sequence should be 162), we plug in n = 5 EXAMPLE.. a(5) = 2·3^(51) = 2·3^4 = 2·81 = 162
