Answer:
The nth term of the sequence is
<h2>9n - 8</h2>
Step-by-step explanation:
The sequence above 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 = 1
d = 10 - 1 = 9 or 19 - 10 = 9 or 28 - 19 = 9
So the nth term of the sequence is
A(n) = 1 + (n - 1)9
= 1 + 9n - 9
= 9n - 8
<h3>A(n) = 9n - 8</h3>

1) Inequality
2) Equation
Step-by-step explanation:
We need to identify the correct description
1) 7x+9<25
The sign < is called greater than and is an inequality symbol
So, the given term is an Inequality
2) 2x-3=5x+12
This is an equation because we equal (=) sign in it.
Solving the equation we can find value of x.
So, the given term is an Equation
