Answer:


Step-by-step explanation:
We have the arithmetic sequence:
100, 110, 120, 130...
And we want to determine the equation for the nth term of the sequence.
The standard form for the nth term of an arithmetic sequence is given by the formula:

Where
is the nth term,
is the first term, and
is our common difference.
From the sequence, we can see that the first term
is 100.
Also, each term is +10 the previous term. Hence, our common difference
is +10.
Therefore, our equation is:
To find the 10th term, we can substitute 10 for n and evaluate. Hence:

Evaluate:

Therefore, the 10th term is 190.
