Best ResponseYou've already chosen the best response.0Not quite. The common difference is the difference between any term and the term immediately before it. In other words, what do you have to add to 5 in order to get 1?

Best ResponseYou've already chosen the best response.0If we use d to represent common difference, then\[d=n _{k}n _{k1}\]In the given question, d=15. What do you get?

Best ResponseYou've already chosen the best response.0Not quite. Shouldn't it be 4?

Best ResponseYou've already chosen the best response.0OK. So the multiplier of n has to be 4. That narrows your choices down to two.

Best ResponseYou've already chosen the best response.0For the first term, n=1. So test the choices with n=1 and see which one gives you the first term, 5.
