Question

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

Answer 1

Answer:

$a_n=2n$

Step-by-step 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 $a_n=2n$.
