nth term for the geometric sequence 4,8,16,... is a_n=4(2)^{n-1}

Step-by-step explanation:

We need to write an equation for the nth term of the geometric sequence: 4, 8, 16 . . .​

The formula to find the nth term of geometric sequence is

a_n=a_1r^{n-1}

Where a_n is nth term

a_1 is 1st term

and r is common ratio

Finding a_1 and r in the sequence 4,8,16,...

a_1=4\\r=\frac{a_2}{a_1}\\r=\frac{8}{4}\\r=2

So, common ratio r is: 2 and a_1 is 4

The nth term is:

a_n=4(2)^{n-1}

So, nth term for the geometric sequence 4,8,16,... is a_n=4(2)^{n-1}

Rewrite and Order 6/7 and 9/11
Aleksandr-060686 [28]

Answer:

6/7 = 66/77

9/11 = 63/77

6/7 is greater than 9/11

Step-by-step explanation:

To give fractions a common denominator you must find the LCM(lowest common multiple) of this two denominators.

So, we have 7 and 11. You must find a multiple 7 and 11 share. This means that the number must be divisible by 7 and 11. The LCM for 7 and 11 is 77.

Now we make both the denominators 77.

Now look at the numerators. Look at 6/7. We multipled 7 by 11 to get 77. Therefore, we must also multiply 6 by 11.

Now we have, 66/77

Do the same with the other fraction but other way around:

11 x 7 so

9 x 7 = 63

So,

63/77

So 6/7 is now 66/77 and 9/11 is now 63/77

Now compare:

66 > 63

66 is bigger so 6/7 is greater.

6/7 is greater than 9/11

motikmotik

Answer:

D.34

Step-by-step explanation:

Let's the A be the 20th board counting from the top of the stack, and B be the 16th board counting from the bottom of the stack. If A is immediately below B, this means B is the 19th board counting from the top of the stack, and also there are 18 other boards that are above B. So the total number of board in the stack would be

16 + 18 = 34

D is the correct answer
