Write the next 2 terms of the Fibonacci sequence starting with 2, 6, ....
Answer:
8, 14
Step-by-step explanation:
Any term in a Fibonacci sequence is found as
[tex]a_{n}[/tex] = [tex]a_{n-2}[/tex] + [tex]a_{n-1}[/tex]
Thus
a₃ = a₁ + a₂ = 2 + 6 = 8
a₄ = a₂ + a₃ = 6 + 8 = 14
The next 2 terms are 8, 14
Answer:
8, 14
Step-by-step explanation:
In a general Fibonacci sequence, any number in the sequence after the first two is the sum of the previous two. Here, we get the 3rd term by adding 2 and 6 to get 8, making our sequence
2, 6, 8
To get the fourth, we repeat the process, adding 6 and 8 to get 14:
2, 6, 8, 14

Find an expression, in terms of n, for the nth term of this sequence.
Answer:
aₙ = 2n² + n + 1Step-by-step explanation:
We observe that the difference of terms is 4, 7 and 15 and next level difference is 4. It means the sequence is quadratic.
We can compare this with simple quadratic sequence
1, 4, 9, 16and find out that doubling each term gives us
2, 8, 18, 32This is close to our sequence, write the terms as follows to find exact rule
The first term:
a₁ = 4 = 2*1² + 2 = 2*1² + 1 + 1The second term
a₂ = 11 = 2*2² + 3 = 2*2² + 2 + 1The third term:
a₃ = 22 = 2*3² + 4 = 2*3² + 3 + 1The fourth term:
a₄ = 37 = 2*4² + 5 = 2*4² + 4 + 1The nth term as per observation above is:

Given:
The side lengths of two cubes are 2.5 yd and 2 yd.
To find:
The side length of third cube.
Solution:
From the given figure it is clear that the cubes are inclined to each other in such a way so that they form a right angle triangle and side length of third cube is the base.
Let x be the side length of the third cube.
Using Pythagoras theorem, we get
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
[tex](2.5)^2=(x)^2+(2)^2[/tex]
[tex]6.25=x^2+4[/tex]
[tex]6.25-4=x^2[/tex]
[tex]2.25=x^2[/tex]
Taking square root on both sides, we get
[tex]x=\pm\sqrt{2.25}[/tex]
[tex]x=\pm 1.5[/tex]
Side cannot be negative. So,
[tex]x=1.5[/tex]
Therefore, the side length of the third cube is [tex]x=1.5[/tex] yd.

The WNBA champions have a twelve-player roster that includes two superstars. If a group of five starting players for this team must include the two superstars, how many different groups of five starting players are there?
Answer:
120 groups
Step-by-step explanation:
Total number of players = 12
Number of superstars = 2
To select a group of 5 players that MUST include the two superstars can be done in how many different ways?
Since the two superstars must always be in the 5 player team
Number of players left to choose = 5 - 2 = 3
Number of players from which selection is to be made = 12 - 2 = 10
Hence, the number of ways of choosing 3 players from 10 ; 10C3
Recall ;
nCr = n! / (n-r)!r!
10C3 = 10! ÷ (10-3)!3!
10C3 = 10! ÷ 7!3!
10C3 = (10*9*8) / (3*2*1)
10C3 = 720 / 6
10C3 = 120 groups
