Given:

The arithmetic sequence: 8, 17, 26, 35, ... ...

To find:

The first 3-digit term of the sequence

Step-by-step explanation:

Given, the arithmetic sequence: 8, 17, 26, 35, ... ...

Then the common difference

= 17 - 8 = 26 - 17 = 35 - 26 = ... ... = 6

Now the next terms of the sequence are

35 + 9, 35 + 9 + 9, 35 + 9 + 9 + 9, ... ...

i.e., 35, 45, 54, 63, 72, 81, 90, 99, 108, ... ...
