Answer:
Step-by-step explanation:
Given that,
...(1)
We need to find the value of 
.
Put n = 1 to find the first term.
Put n = 2 to find the second term.
Put n = 3 to find the third term.
Put n = 10 to find the tenth term.
It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :
We have, n = 10, a = 5 and 
So,
So, the value of is equal to 280.
Answer:
0, 1, 2
Step-by-step explanation:
So, since there are three consecutive integers, you have the equations
x, x+1, x+2 where x is the smallest number.
The greatest of the three integers= x+2
Finish setting up your equation;
2(x+x+1)=x+2
Combine like terms;
2(2x+1)=x+2
Distribute;
4x+2=x+2
3x=0
x=0
x+1=1
x+2=2
Hope this helps:) Have a good day!

Answer:
1/3
Step-by-step explanation:
Probability of solving ten problems by Carl
Given
Total number of problems = 20
Number of problems studied by Carl = 15
Number of problems out of the 20 set of problem coming in test is 10
Case I - All ten problems come from the set of known 15 question
10/15 * 10/20 = 1/3
