Using the variable n for the term, describe the sequence.

= 10n

Step-by-step explanation:

The nth term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = a₂ - a₁ = 20 - 10 = 10 , then

= 10 + 10(n - 1) = 10 + 10n - 10 = 10n
