Step-by-step explanation:
The given sequence is 2, 4, 6, ....
We need to write an explicit formula for
. 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 :

Where
n = 1,2,3....
Hence, the explicit formula is
.
