Write the explicit rule. remember to simplify and do not put spaces in your answer.

sequence : 32,52,72,92 ...

a n =

a (n) = 12x+20

Step-by-step explanation:

tbh I'm not sure if this is the form they wanted it in but assuming this is an arithmetic sequence you can find the equation by finding the n-1 (assuming 32 is the first term 12 would be the zero term) term and then adding the common difference (20) to get 12x+20.

However that might be the recursive way so do double check your options.
