Question

9=100 8=143 6=165 8=? give explanation​

Answer 1

Answer:

160

Step-by-step explanation:

The value of 5 is 160.

By calculating the first difference in between the values given, the values obtained are 43, 19, 3, and -5.

The second difference gives 24, 16 and 8.

The third difference gives 8 and 8, which are all non-zero differences.

So, it is a 3rd power polynomial = Ax^3 + Bx^2 + Cx + D with equations of:

729A + 81 B + 9 C + D = 100

512A + 64B + 8C + D = 143

343A + 49B + 7 C + D = 162

216A + 36B + 6C + D = 165

Therefore, the polynomial is:

(-4/3)x^2 + 20x^2 - (28/13)x + 295

X = 5, which is evaluated as 160.

Thus, the value of 5 = 160.

Answer 2

Your explanation is here
The value of 5 is 160

By calculating the first difference in between the values,
The values obtained are 43,19,3,and-5

Now the second difference gives 24,16 and 8

The third difference gives 8 and 8,
Which are all non zero differences

Sooo
It is a 3rd power polynomial
=Ax^3+Bx^2+Cx+D

WITH THE EQUATIONS

729 A + 81 B + 9 C + D = 100

512 A + 64 B + 8 C + D = 143

343 A + 49 B + 7 C + D = 162

216 A + 36 B + 6 C + D = 165
Therefore the polynomial is:

(-4/3)x^2+20x^2-(28/13)x+295

Now x = 5, which evaluated as the number 160

Soo, the answer is
THE VALUE OF 5 = 169

I think my explanation is good
