Question

Write an explicit formula for an, the n^th
term of the sequence 2, 4, 6, ....

Answer 1

`a_n=2n`

Explanation:

The given sequence is 2, 4, 6, ....

We need to write an explicit formula for
`a_n`. The firts term is 2, second term is 4 and third term is 6 and so on.

Each term is 2 greater than the term before it. Thus we can write it as follows :

`a_n=2n`

Where

n = 1,2,3....

Hence, the explicit formula is
`a_n=2n`.
