Enter a recursive rule for the geometric sequence.
4, −16, 64, −256,
a1=
an=

Step-by-step explanation:

Given a G.P series i.e geometric sequence

4, −16, 64, −256, ...

We have to find the recursive rule for the geometric sequence.

We know that   is the first term of the sequence.

Here

As, the nth term of Geometric progression is

where r is the common ratio

Hence the recursive formula is

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
