find the first eight numbers of the arithmetic sequence in which the sum of the first and seventh terms is 40 and the product of the first and fourth terms is 160
we cannot give you a full solution, of course, because you have to hand this in. i will give you a hint.
recall that the terms of an arithmetic series are of the form
for
where is the nth term, is the current number of the term, is the first term, and is the common difference.
use that to find the formula for the first 8 terms, then formulate them as the question asked to find what the question asked for
example, the first term is
the second is
the third is ...
