Question

Tell whether the sequence is arithmetic if it is identify the common difference -7,-3,1,5

Answer 1

Yes it is an arithmetic sequence because a specific number is being added to each previous number. So starting from -7, if you add 4 you get -3, add 4 again to get 1, add 4 one last time to get 5

So, yes the sequence is arithmetic and the common difference is +4
