Answer:
an = 7n -10
Step-by-step explanation:
In general, the iterative rule for an arithmetic sequence with first term a1 and common difference d is ...
... an = a1 + (n-1)d
Your sequence has a1 = -3, and d = 7, so the rule can be written ...
... an = -3 + 7(n -1)
and simplified to ...
... an = 7n -10
Divide the numerator and denominator both by any common factor that
they have. If it's their greatest common factor, then one time does it.
If it's a smaller common factor, then you may have to do it more than once.
When they have no common factor left except ' 1 ', then the faction is in its
simplest form.
