gizmo_the_mogwai [7]
Definition of additive inverse.- If two numbers are added together and the sum is zero, they are the additive inverse of each other. 


<span>......................................... IF A + B = 0 , they are the additive inverse of each other. 
</span>

<span>Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. </span>

<span>......................................... A.B = 1 , they are the multiplicative inverse of each other. 
</span>

<span>Example of: </span>

A n =−1+3(n−1) an=−1+3(n−1) what is the 55 term in the sequence
Sindrei [870]
ANSWER

a_{55}=161


EXPLANATION

The general term for the sequence is


a_n=-1+3(n-1)


To find the 55th term, we have to substitute
n = 55
in to the general term and simplify.



This implies that,

a_{55}=-1+3(55-1)



a_{55}=-1+3(54)




a_{55}=-1+162



a_{55}=161


Therefore the 55th term is 161.

monitta

Answer:

z=-7

Step-by-step explanation:

-9+8*14z+8*2=7*17z+7*8

-9+112z+16=119z+56

112z+7=119z+56

-112z       -112z

7=7z+56

-56    -56

-49=7z

:7     :7

z=-7
