Answer:
The value of the length of AC is 14
Step-by-step explanation:
When points are collinear, it simply means that the points lie on the same straight line.
In this question , we have three points which lie on same straight line.
These are points A, B and C with B between A and C.
Thus the length AC can be obtained by adding the length of AB to the length of BC
Mathematically, the value of the length of AC will be 8 + 6 = 14
Answer:
(Same problem, just with different parts missing; make sure you are looking at the line that goes with <em>your</em> problem)
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number.
We are told that a=4 and d=6 so we have:
a(n)=4+6(n-1), so the 39th term is:
a(39)=4+6(38)
a(39)=4+228
a(39)=232
