Well, if that is a comma in the number, it is already rounded. If the comma is supposed to be a decimal, the answer would be $57.
        
             
        
        
        
Here's a list that might help:
Odd functions: sinx, tanx, cotx, cscx
Even functions: cosx, secx
        
             
        
        
        
R - 10/3 + 1/2 = -11/6...if u multiply everything by the common denominator 6, it will get rid of the fractions.
(6)r - 6(10/3) + 6(1/2) = 6(-11/6)
6r - 60/3 + 6/2 = - 66/6...simplify
6r - 20 + 3 = - 11
6r - 17 = -11
6r = -11 + 17
6r = 6
r = 6/6
r = 1 <===

Answer:
a_n = 28-2n
Step-by-step explanation:
Given sequence is:
26,24,22,20
We can see that the difference between consecutive terms is same so the sequence is an arithmetic sequence
The standard formula for arithmetic sequence is:

Here,
a_n is the nth term
a_1 is the first term
and d is the common difference
So,
d = 24-26
= -2
a_1 = 26
Putting the values of d and a_1

Hence, the recursive formula for given sequence is: a_n = 28-2n ..
