It depends if x is positive or negative and the same as in y
Answer is -6(see photo for step by step):
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 ..
Since you want to put this in simplest form ... the easiest way you can do it is
3 (100) + 97
So, step 1] 3(100)= 300
Step 2] 300 + 97 = 397
Answer : 397 over 100

There's other ways too, but it'll take me all night to finish it
