Answer: 7
Step-by-step explanation:
For c, we are given this sum from 1 to 3 of 
. 1/2 is a constant , therefore, we can move it outside of the summation.
*I hope you can understand what I'm saying. I can't figure out how to type in summations into the equations section.
1/2∑₁³n²
This means you would multiply the sum of n² from 1 to 3 by 1/2.
We are told n=1 to n=3 so we would plug 1, 2, 3 into n.
1²=1
2²=4
3²=9
We would add them together since that is what the sum sign tells us to do.
1+4+9=14
Now that we know the sum, we multiply it with 1/2
14/2=7
Answer:
15/32
3/4 x 5/8 = 15/32 in fraction form.

$136.28
Step-by-step explanation:
Answer:
- Next two terms of the sequence is 20 and 24.
Step-by-step explanation:
The arithmetic sequence is 6, 10, 14 , 16
First term (a) = 6
Subtract the first term from the second term:
Subtract the second term form the third term:
Subtract the third term from the Fourth term:
Here, You will notice that each time you move from one number to the next one it increases by four. So, the difference between one and the next term is four.
So,
Next two terms are:
⟶ 16 + 4 = 20
⟶ 20 + 4 = 24
Hence,
- <u>Next two terms of the sequence is 20 and 24.</u>
