Given:
The sequence is:
To find:
The formula for the nth term in the given sequence.
Solution:
We have,
The given sequence can be written as
The sign are alternative and the absolute value of each term can be defined by the expression 
, where n is a natural number.
So, the required formula is:
Therefore, the formula for nth term in the given sequence is .
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients.
13. 10z + 7z - 19z² - 5z² - 17z
first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this:
-19z² - 5z² +10z + 7z - 17z
Now simplify the coefficients:
-24z² + 0z
you can omit the 0z and your simplified answer is
-24z²
Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.
Answer:
CA = 32
Step-by-step explanation:
By intersecting chords theorem:
CA = 14 + ( 3 + 3x)
CA = 14 + ( 3 + 3*5)
CA = 14 + ( 3 + 15)
CA = 14 + 18
CA = 32
The resulting expression for the variable v is u - e - g
<h3>Subject of formulas</h3>
Subject of formula is a way of representing a variable in terms of another variable.
Given the expression below;
u=e+g-v
We are to make v the subject of the formula
Subtract e + g from both sides
u- (e + g)=e+g-v - (e+g)
u - (e+g) =v
Expand the left hand side of the expression
u - e - g = v
Swap
v = u - e - g
Hence the resulting expression for the variable v is u - e - g
