Question

Determine whether the sequence is an arithmetic sequence. If yes, identify the common difference 7,10,13,16

Answer 1

yes it is an arithmetic sequence.

To identify if it is a sequence ther must be a repetitive pattern.

in this case there is always a pattern of adding 3 to the term that was before. .

To find the common difference simply substract one term from the one before

$13-10=3$
