Answer:
communitive property of addition
Step-by-step explanation:
The community property of addition states: a+b=b+a
This basically means that when you add two numbers, the order of when you add them does not occur.
An nth term in arithmetic sequence can be calculated using the following equation:
a(n) = a(1) + (n-1)d
Where a(n) = nth term, a(1) = first term, n= position of a(n), and d= common difference.
In the current task, a(1) = 1.6, n=100, d= 2.3-1.6=3.3-2.3 = 0.7
Therefore
a(100) = 1.6+(100-1)*0.7 = 70.9
