Postby NObabe4real on Wed Dec 08, 2010 2:51 am

Complete to find the given term of each arithmetic sequence.

1/8, 1/4, 3/8, 1/2, 5/8,...
Find the 25th term.
n=_____, a1=_____, d= _____
a25= _____+(___-1)______
=______ + _______ = ______

Please I need help and cannot figure out the common difference between the set of numbers.

To find the common difference, subtract. What is 1/4 - 1/8? What is 3/8 - 1/4? And so forth. (You want to do at least two subtractions, to confirm that the differences are indeed "common"; that is, that they are the exact same value.)
