I think it could be b cause it does have sum solution or it could be A at the same time so try to used the calculator and if it comes up with less then then it could be A if it comes up with more then, then it could be B

Fill in the missing number: 2, 8, 27, 85, 260, _, 2365

Each number is mutliplied by 3 and then numbers 2,3,4,5,... are added successively.

2*3+2=8

8*3+3=27

27*3+4=85

85*3+5=260

260*3+6=786

So it's 786.

Btw, the general formula for this sequence is $a_n=\dfrac{1}{12}(-6n+13\cdot3^n-9)$

Given the literal equation ab/a+b = c , with b = –1 + a, what is the value of c if a = 5?

Nesterboy [21]

The solution would be like this for this specific problem:

ab/a+b = c

b = -1 + a

for c:
(5(-1 + 5))/(5 + (-1 +5))
5(4)/ 5 + 4
20 / 9

The correct answer between all the choices given is the first choice or letter A. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

SOVA2 [1]

Answer:

The measures of angles of triangle MNP are

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the measure of arcs AB, BC and AC

we know that

The inscribed angle is half that of the arc it comprises.

$\gamma=\frac{1}{2}[arc\ AB] ----> arc\ AB=2\gamma\\\alpha=\frac{1}{2}[arc\ BC] ----> arc\ BC=2\alpha\\\beta=\frac{1}{2}[arc\ AC] ----> arc\ AC=2\beta$
