a_15 = 90
a_n = 6n
Step-by-step explanation:
Given sequence is:
6, 12, 18, 24,...
First of all we have to find the common difference. The common difference is the difference between consecutive terms of an arithmetic sequence.
Here,

The general form for arithmetic sequence is:

Putting the values for a_1 and d

<u>a) Find a15</u>

<u>b) Write an equation for the nth term.</u>
The equation is: a_n=6n

Answer:
I need help with this question too do you know the answer
Step-by-step explanation:
The possible values of z is an illustration of the sum operator
The sum of all possible values of z is 17
<h3>How to determine the possible sum of z?</h3>
The conditions in the question are:
x <= y <= z
xyz = 2(x + y + z)
Using the trial by error method, the possible values of x, y and z are:
- x = 1 , y = 3 , z = 8
- x = 1 , y = 4 , z = 5
- x = 2 , y = 2 , z = 4
The sum of the z values are:
z = 8 + 5 + 4
Evaluate the sum
z = 17
Hence, the sum of all possible values of z is 17
