Write the first four terms of the sequence whose general term is given by:

{eq}a_n = 4_n + 1 {/eq}

{eq}a_1 {/eq} = ?

Question:

Write the first four terms of the sequence whose general term is given by:

{eq}a_n = 4_n + 1 {/eq}

{eq}a_1 {/eq} = ?

Arithmetic Sequence:

An arithmetic sequence is a series of numbers formed when the next term formed by adding a constant number to the preceding term. For example, the sequence {eq}0, 2, 4, 6, 8, 10 {/eq} is an arithmetic sequence since the difference between a term and its preceding term is 2.

We have the series:

$$a_n = 4_n + 1 $$

The first four terms of the sequence will be defined by {eq}a_1 {/eq} for {eq}n=1 {/eq}, {eq}a_2 {/eq}...
