Q.7 Write variable expressions for arithmetic sequences
Write an expression to describe the sequence below. Use n to represent the position of a term in
the sequence, where n = 1 for the first term.
-8, -16, -24, -32, ...

Which equation represents the partial sum of the geometric series?

How to do this , and can some one explain

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
