can u guys help me plzz
tell whether the see the sequence is arithmetic. If it is, what is the common difference?
15,19,23,27…..

Answer 1

It is arithmetic. The sequence increases by 4.

Answer 2

When you look at the sequence you see that it is increasing. So each term is either

1) being added to by a constant (common difference) -- Arithmetic
2) being multiplied by a constant (common ratio). -- Geometric

Here you see that each term is increasing by 4, the common difference. Which also means the sequence is Arithmetic.

Answer 3

ok thank you
