an= 10n+90

a10= 190

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.
