Answer:
Graph 1 goes with the equation 
Graph 2 goes to the equation y = 
Graph 3 goes to the equation y = x + 10
Answer:
x = -100
You'd multiply both sides by 5/(-4) to solve in one step.
Given:
The explicit function is:

To find:
and first 5 terms.
Solution:
The explicit formula a geometric sequence is:
...(i)
Where, a is the first term and r is the common ratio.
We have,
...(ii)
On comparing (i) and (ii), we get


And,

For
,




For
,




Similarly, substituting
, we get



Therefore,
and the first five terms are
.
Whole numbers, rational numbers and irrational numbers are types of real numbers.
Whole number examples; 0, 1
Rational number examples; 1/2, 0.25
Irrational number examples; √25, π PI
WHOLE numbers are easiest for me to identify.
