There are many possible answers. Some are
A: Un = (2n3 - 15n2 + 34n - 18)/3
B: Un = 2 - mod(n, 2)
C: Un = 1.5 + 0.5*(-1)n
1/2
The phrase "first difference" is usually associated with a sequence of numbers: a(1), a(2), a(3), a(4), ... . The sequence may have a simple rule for generating the numbers , a complicated rule or, if it is a random sequence, no rule at all.The sequence of first differences is a(2)-a(1), a(3)-a(2), a(4)-a(3), ...
2+2=4 2+a=4 A math equation is any mathematical sentence that has an equal sign, numbers, or variables in it ;)
MIlk from the cow is approximately 3.5% fat ( average; can run from 1 to 6%). There isn't a math equation, but lowering the fat brings the percentage down from 3 to 2, or 1.
2 + 2
Difference in math means subtraction. To express the difference between 6 and 2 you would use the equation 6 - 2 = 4.
You just have to follow the rule of quadratic functions. Example y = mx+b is the rule for linear functions. ax^2+bx+c is the rule of quadratic equation.
The equation 5X plus 4 X-2 -2X 2 X-1 plus3 X plus 2 equals to 2. This is college math.
An expression is the sum (or difference) of two or more terms. Example 3x + 2y is an expression.It is a mathematical statement e.g 7=6+1 THE WHOLE THING IS AN EQUATION but the 6+1 is a expression.You can only have an expression if there is not an = signYes the 6 + 1 part is an expression. If you have an = sign or any of the other inequality symbols (,...) it is no longer an expression but a full math sentence.
The slope of the equation 2 times 2 take away 1 times 4 would be 3. This is a math problem.
The slope intercept form through 23 and 15 would be 5. This is considered as a math equation.
2 x 41 = 82
