Answer:
(c) 3360
Step-by-step explanation:
Given
The above arithmetic series where:
--- first term
--- the common difference (18 - 12 = 6)
--- The last term
Required
The value of the series
First, we calculate n using:
This gives:
Collect like terms
Divide both sides by 6
Make n the subject
The sum of the series is:
So, we have:
Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Nonlinear functions are all other functions. An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.
Answer:
x = -3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
