Consider the sequence : 41,29,17,5
is this sequence
a. arithmetic
b. geometric
c. exponential

part b:
it can be defined recursively by the function:
a: an=an-1+12
b: an=an-1-12
c: an=12a^n-1

part c: and a^1 equals
a: 53
b: 41
c: -12

Step-by-step explanation:

A]

Each term goes down by 12 from the previous term. The sequence is arithmetic - B.

B]

The correct recursive function is

An = A_(n-1) - 12

which means that the correct answer is B

C]

The first term, if that is what your nomenclature means, is 41.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
