Answer:
19th term = ar^18
19th term = 774,840,978
Step-by-step explanation:
First term, a = 2
Common ratio, r = 3
nth term of a geometric sequence = ar^(n-1)
19th term = ar^(19-1)
19th term = ar^18
= 2 × 3^18
= 2 × 387,420,489
= 774,840,978
19th term = 774,840,978
 
        
             
        
        
        
Answer:
True answer: -24
Step-by-step explanation:
<em><u>Showing the error</u></em>
-16-2(-2) – 12   First you need to multiply
8(-2) - 12   The error here is that the wrong numbers are multiplied together
-16-12    Add the negatives together
-28  Your answer (the incorrect one)
<em><u /></em>
<em><u>The correct way of solving it</u></em>
-16 -2(-2) - 12  Multiply into the parenthesis 
-16 + 4 -12   Add the first two numbers
-12 - 12  Add the numbers together
-24  The answer

Step-by-step explanation:
 
        
             
        
        
        
Kylie's first month collection, a1= $ 145
Second month collection , a2= $145+ 20
Third month collection, a3  = $145 +2*20
.
.
.
.
so for n months collection = an-1+20 
We get an= 20 + an-1  and a1=145
