The explicit rule for the arithmetic sequence for the sequence is a(n) = 3n + 2.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have given:
and


The above expression represents the common ratio:
d = 3
First term:
a = 5
The explicit rule for the arithmetic sequence:
a(n) = 5 + (n - 1)3
a(n) = 3n + 2
Thus, the explicit rule for the arithmetic sequence for the sequence is a(n) = 3n + 2.

#SPJ1
X + 2y = 11
2x + y = 31
x = 11 - 2y
2(11 - 2y) + y = 31
22 - 4y + y = 31
3y = - 9
y = - 3
x = 11 - 2(-3)
x = 11 + 6
x = 17
The answer to the question is c
Answer:
2
Step-by-step explanantion:
You sustitute 20 for s to get 20 = d + 18, subtract 18 from both sides and you get d = 2.
