Write the following arithmetic series in summation notation.
9+13+17+....+45

Please help

Answer 1

What do we do to 9 to get 13? Add 4 yes? How about getting from 13 to 17? It looks like we are adding 4 every time.

Answer 2

so the question mark would be 4 correct?

Answer 3

No the question mark at the bottom of the summation is the initial n value to give the first term in the series.

Answer 4

@shawmoes are you saying to add 9 to n every time?
