Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 2, comma, 10, comma, 18, comma, point, point, . 2,10,18,...
To determine if the sequence is arithmetic or geometric, we need to check if there is a constant difference between consecutive terms.
The common difference between 2 and 10 is 10 - 2 = 8.
The common difference between 10 and 18 is 18 - 10 = 8.
Since there is a constant difference of 8 between consecutive terms, the sequence is arithmetic.
The common difference in simplest form is 8.
