Solution

Hence, the first five terms of the sequence are 3, 11, 35, 107, and 323.

The corresponding series is 3 + 11 + 35 + 107 + 323 + …

a_{1} = a_{2} = 2, a_{n} = a_{n - 1} - 1, n > 2

a_{1} = a_{2} = 2, a_{n} = a_{n - 1} - 1, n > 2

Write the first five terms of each of the sequence and obtain the corresponding series :

$a_{1} = 3, a_{n} = 3 a_{n - 1} + 2 for all n > 1$

a_{1} = - 1, a_{n} = \frac{a_{n - 1}}{n}, n \geq 2

a_{1} = 3, a_{n} = 3 a_{n - 1} + 2

n > 1
