The given pattern is a regressive arithmetic progression with 3 numbers of terms. The first term is 7.5 and the common difference between the value is -1.25.
Given that,
In the question, a pattern is given 7.5 6.25 5.
It is to be determined the nature of the given pattern.
What is arithmetic progression?
Arithmetic progression is the series of numbers that have common differences between preceding values.
What is geometric progression?
Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
Here, in the question given pattern is 7.5, 6.25, and 5.
First term = 7.5
Common difference between preceding value = 7.5 - 6.25 = 6.25 - 5
Common difference = -1.25
Implies the given pattern is a regressive arithmetic progression.
Thus, the given pattern is a regressive arithmetic progression with 3 numbers of terms. The first term is 7.5 and the common difference between the value is -1.25.
