Question from francis, a student:

which term of the series 152?

Hi Francis,

To obtain each term of the series you add 5 to the previous term so the next few terms are 2+7+12+17+22+...

How many times do you add 5 to get from 2 to 152? Which term is 152?

As a check ask yourself, how many times do you add to get from 2 to 22? Which term is 22?

Did you get the correct answer? If not what is incorrect with your process?

I hope this helps,
