P = 1/4S + 2

9 = 1/4S + 2
-2 -2
--------------------

7 = 1/4S
4(7=1/4S)

28=S

There are 28 students int the class

What is the missing term in the geometric sequence?

liubo4ka [24]

Solution:
formula : an=a1(r)^n-1
n - number of term that is unknown
a1 - first term
r - second term divided by the first term
a1=-6
a2=24
a3=?
a4=384
a5=-1536

a3=-6(24÷-6)^3-1
a3=-6(-4)^2
a3=-96
therefore the 3rd term is -96 (c)

7 squared by 2 +3(4 squared by 2 +3+2)

VLD [36.1K]

Answer:

The answer of the given expression is $\frac{127}{2}$ .

Step-by-step explanation:

Given $\frac{7^2}{2}+3(\frac{4^2}{2}+3+2)$ .

Step 1 : Firstly we have to solve for brackets, adding the fraction with digits. For this we have to multiply 3 and 2 by 2 by 2 which gives the same denominator.

$\frac{4^2}{2}+3+2=\frac{16}{2}+3+2\\\frac{16}{2}+\frac{3\times2}{2}+\frac{2\times2}{2}= \frac{16}{2}+\frac{6}{2}+\frac{4}{2}=\frac{26}{2}$

Step 2 : Fraction under the brackets is solved now we have to multiply the result with 3 to remove the brackets.

$\frac{26}{2}\times3=\frac{78}{2}$

Step 3 : Now we have an expression with same denominator, here simply add and we get the result.

$\frac{7^2}{2}+\frac{78}{2}=\frac{49}{2}+\frac{78}{2}=\frac{127}{2}$

Hence the solution for given expression is $\frac{127}{2}$ .
