The pattern increases by 4, then 6, then 8
Since the rate is changing, the function has a square in it.
If you plug 1, 2, and 3 into the functions below, n^{2} +n is the one that works.

The answer is n^{2} +n

13) Here, Sequence : -2, -6, -18, -54
Common Ratio = a₂/a₁ = -6/-2 = 3
As the expression is in negative sign, it's sequence will be -3ˣ
Where x = number of terms in the sequence [ By this rule, you can calculate the unknown nth number]

<span>In short, Option C is your answer!!!!

14) Here, a</span>₂-a₁ = 6-2=4, a₃-a₂ = 12-6 = 6
So, difference is increasing by 2 at each step, as it's not arithmetic, It must deviate by the square on it. As only one option has square on it, it will be
 (n²+n)

In short, Option B is your final answer.

15)V = 2πr²h
 h = V / 2πr²

In short, Option D is your final answer.

Hope it helped, Please Let me know, if you have some doubts!!

2.

3. K (985 is the greatest 3-digit number)

4. J (67176 is the palindrome with the greatest number of digits)

5. K (3579 is the greatest number of odd numbers in counting order)

Step-by-step explanation:

I couldn't find an answer to number 2, sorry! You should probably go over it one more time and check that all these answers are correct. You might catch something I missed :)

Hope this helps!

In a large apartment building, 35 of the apartments have a balcony and 55 do not.
Masteriza [31]
Hello!

You first have to find the total amount of apartments

35 + 55 = 90

There are 90 apartments

Then you find the percentage of them have a balcony

You do this by taking the amount of apartments that have a balcony over the total amount of apartments

35/90 = 0.39

0.39 as a percent is 39%

The answer is 39/100 or 39%

Hope this helps!

Simplify the expression.<br><br> (−5g5h6)2(g4h2)4
Colt1911 [192]

We have to simplify the expression here. The expression given,

(-5g^5h^6)^2(g^4h^2)^4

Now to find (-5g^5h^6)^2 we will use power of a product property. We have to distribute the power here. We will get,

(-5g^5h^6)^2 = (-5)^2(g^5)^2(h^6)^2

= 25(g^5)^2(h^6)^2

Now we will use power of a power property. If given (a^m)^n we will have to multtiply the powers and we will get a^{mn}. So we will get here,

25(g^5)^2(h^6)^2 = 25 g^{10} h^{12}

Now the next part is (g^4h^2)^4

By using power of a power property we will get,

(g^4)^4(h^2)^4 = g^{16}h^8

Now we have to multiply them.

(25g^{10}h^{12}  )(g^{16}h^8)

Now we have to use product of powers property. If we have same base them we will have to add the exponents there. The formula is (a^m)(a^n) = a^{(m+n)}. So we will get here,

25(g^{10} g^{16})(h^{12}  h^{8})

25g^{(10+16)} h^{(12+8)}

25g^{26}h^{20}

So we have got the required simplified answer here.

The simplified answer is 25g^{26}h^{20}.
