X is 20 because if you do 7x + x +20 = 180 you would have 8x + 20 = 180 the subtract 20 which = 160 then divid 8 by 160 which = 20
Answer:
The explicit formula for the sequence is
<h2>44 - 6n</h2>
Step-by-step explanation:
The above sequence is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
From the question
a = 38
d = 32 - 38 = - 6 or 20 - 26 = - 6 or
14 - 20 = - 6
So the formula for the sequence is
A(n) = 38 + ( n - 1)-6
= 38 - 6n + 6
We have the final answer as
<h3>A(n) = 44 - 6n</h3>
