Answer:
25 is the 8th term.
a8=4+(8-1)3
Explanation:
4, 7, 10, 13
The formula in an explicit formula is
an=a1+(n-1)d
n is the term that you want to find, in this case it would be 8. So replace the n in an with "8."
a1 is the first term of the sequence, and for this sequence it would be 4. Replace a1 with "4."
For the n in (n-1), also replace with n with "8."
And d is the common difference between each term. We can see that from 4 to 7 is 3, from 7 to 10 is 3, from 10 to 13 is also 3. So we know that the common difference is 3 in this sequence. d would be replaced by "3"
a8=4+(8-1)3
a8=4+(7)3
a8=4+21
a8=25
So the 8th term of the sequence would be 25.
