What is the common difference in the sequence -9, -4, 1, 6, 11,...?

$\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

The common difference is a number you add or subtract in order to get to the next term; in this case, we add.

The common difference of this arithmetic sequence is 5.

So in order to get to the next term, we add 5.

-9+5=-4

-4+5=1

1+5=6

6+5=11, etc.,

Henceforth the common difference of this sequence is 5.

Good luck.
