What fomula can be used to describe the sequence? -2/3,-4,-24,-144

Lunna [17]

This is a geometric sequence with n th term formula

$a_{n}$ = $a_{1}$ $(r)^{n-1}$

where r is the common ratio and $a_{1}$ the first term

here $a_{1}$ = - $\frac{2}{3}$ and

r = $\frac{-144}{-24}$ = $\frac{-24}{-4}$ = 6

$a_{n}$ = - $\frac{2}{3}$ $(6)^{n-1}$

or in terms of x

f(x) = - $\frac{2}{3}$ $(6)^{x-1}$

Suppose for some value of x the solution to the equation 2.5(y−x)=0 is y = 6. What must be true about x?

Varvara68 [4.7K]

Step-by-step explanation:

In this case, you input the value of y (y = 6) into the equation ( 2.5(y-x)= 0)

2.5(6-x) = 0

Open the bracket,

(2.5×6)-2.5x= 0

Collect like terms.

2.5x= 2.5×6

Divide both sides by the coefficient of x (2.5)

x = 6

So,

x= 6 is true.

Substituting 6 for x in the equation,

2.5(6-6)= 0

2.5•0 = 0

0= 0

Which is also true.
