Write a recursive formula for the sequence below. Use the variable "n" for your formula in your answer. {2, -8, 32, -128, 512, ... }

============================================

Explanation:

The first line of the answer says "the first term is 2".

The second line says "take any term and multiply by -4 to get the next term".

The represents the nth term while is the term just before it.

The second line shown above is the same as writing

---------------

The -4 is found by dividing any term over its previous one

-8/2 = -4

32/(-8) = -4

-128/32 = -4

512/(-128) = -4

This shows the common ratio is -4 and this sequence is geometric.

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

x = 25/2304
