From the given problem, it says show how to make a ten to solve 13-7.
Subtracting 13 to 7 gets 6. In order to get a 10, subtract 10 by 6. 10-6 = 4.
So, you need to add 4 in order to make a ten.

Answer:
an=9+(n−1)3, an=3n+6
Step-by-step explanation:
Arithmetic Sequence:
d=3
This is the formula of an arithmetic sequence.
an=a1+d(n−1)
Step 1: Substitute in the values of
a1=9 and d=3.
an=9+(3)(n−1)
Step 2: Simplify each term.
an=9+3n−3
Step 3: Subtract 3 from 9.
an=3n+6
