Find the common difference of the arithmetic sequence and then write the linear function (explicit formula) that represents the relationship REMEMBER the y-intercept is the 0 term in a sequence you will need to work back one value to identify the b value

1) 18,22,24,27

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
