The initial value of the geometric sequence of the points shown on the graph is 2.
What is the initial value of a geometric sequence?
The initial value of a geometric sequence is the difference between the first term and the second term. If we subtract the first term (a) from the second term.
From the given information:
- The points give a straight line graph;
Where;
- The values of x are progressive from; 1, 2, 3
- However, the values of y change from the second to the third term.
But the initial difference between the first term of y i.e. 2 and the second term (4) is the common ratio (r)
r = 4/2
r = 2
