Answer: 793

Step-by-step explanation:

1 + 8 = 9

9 + 8 = 17

17 + 8 = 25

If 25 is the fourth term in the sequence, and the formula is + 8 for every term, then you need to find 96 more terms with + 8.

96 * 8 = 768

768 + 25 = 793

Answer:

The 100th term is 793.

Step-by-step explanation:

Notice that this arithmetic sequence has first term [tex]a_1=1[/tex]

and common difference [tex]d=8[/tex] (since each consecutive term is built by adding "8" to the previous one)

Recall the general formula for the nth term of a sequence:

[tex]a_n=a_1\,+(n-1)\,d[/tex]

therefore, for our articular case, the term 100th can be obtained with:

[tex]a_n=a_1\,+(n-1)\,d\\a_{100}=1\,+(100-1)\,8\\a_{100}=1\,+(99)\,8\\a_{100}=1\,+792\\a_{100}=793[/tex]
