Kong took 15, percent fewer seconds than Nolan took to complete his multiplication timed test. Kong took 85
Evgen [1.6K]

Hello!


If Kong took a 85 second and we if Nolan took 15 slower then Nolan took a 72.25 second test. First you would find 14 percent of 85 then that is 12.75. Minus that from 85 and you get 72.25.


Hope It helps!

Write the explicit formula for the sequence below and use it to find the 16th term:
mario62 [17]

Given:

The sequence is:

6, -24, 96, -384,...

To find:

The explicit formula for the given sequence and then find the 16th term.

Solution:

We have,

6, -24, 96, -384,...

The ratio between two consecutive terms are:

\dfrac{-24}{6}=-4

\dfrac{96}{-24}=-4

\dfrac{-384}{96}=-4

The given sequence has a common ratio. So, the given sequence is a geometric sequence with first term 6 and common ratio -4.

The explicit formula of a geometric sequence is:

a_n=ar^{n-1}

Where, a is the first term and r is the common ratio.

Putting a=6, r=-4 in the above formula, we get

a_n=6(-4)^{n-1}

We need to find the 16th term. So, put n=16 in the above formula.

a_n=6(-4)^{16-1}

a_n=6(-4)^{15}

a_n=6(-1073741824)

a_n=-6442450944

Therefore, the explicit formula for the given sequence is  a_n=6(-4)^{n-1} and 16th term of the given sequence is -6.442450944.
