a5=8+ (5-1) 3
what is the common differance
The given expression, a5 = 8 + (5-1) 3, does not represent a sequence, so there is no common difference. It seems to be a mathematical expression to evaluate a particular term (a5) in a sequence, but without more context, it is not possible to determine a common difference.
To find the common difference in this equation, we first need to determine if it is an arithmetic sequence.
An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is always the same. In other words, each term can be found by adding (or subtracting) a constant value, known as the common difference, to the previous term.
Let's simplify the equation:
a5 = 8 + (5 - 1) * 3
First, evaluate the parentheses:
a5 = 8 + 4 * 3
Next, perform the multiplication:
a5 = 8 + 12
Finally, add:
a5 = 20
Since this equation only represents a single value (a5 = 20), it does not form a sequence with multiple terms. Therefore, it doesn't have a common difference.
The given expression is:
a5 = 8 + (5 - 1) × 3
To find the common difference, we need to determine if this expression represents an arithmetic sequence.
However, the given expression is not an arithmetic sequence. It appears to be a single equation with variable "a5" defined in terms of constants and arithmetic operations. It does not follow the typical form of an arithmetic sequence, where the common difference is constant.
Therefore, in this case, the concept of a common difference does not apply to the given expression.
