Woo-Jin and Kiran were asked to find an explicit formula for the sequence 64\,,\,16\,,\,4\,,\,1,...64,16,4,1,...64, comma, 16, c
olya-2409 [2.1K]

Answer:

f(n)=64(\frac{1}{4})^{n-1}

Step-by-step explanation:

The given sequence is

64, 16, 4, 1

r_1=\dfrac{a_2}{a_1}=\dfrac{16}{64}=\dfrac{1}{4}

r_2=\dfrac{a_3}{a_2}=\dfrac{4}{16}=\dfrac{1}{4}

r_3=\dfrac{a_4}{a_3}=\dfrac{1}{4}

It is a geometric series because it has a common ratio r_1=r_2=r_3=\dfrac{1}{4}.

First term is 64.

The explicit formula of a geometric series is

f(n)=ar^{n-1}

where, a is first term and r is common ratio.

Substitute a=64 and r=1/4 in the above function.

f(n)=64(\frac{1}{4})^{n-1}

Therefore, the required explicit formula is f(n)=64(\frac{1}{4})^{n-1}.

Shari is adding these fractions: <br><br> 1/3 + 1/4<br><br> What's her next step?
Arlecino [84]

Her next step is to find a common denominator. Remember that if you multiply a number to the denominator, you'll have to multiply it to the numerator too:


1/3(4/4) + 1/4(3/3)


4/12 + 3/12


Simplify. Combine like terms


4/12 + 3/12 = 7/12


7/12 will be final solution



hope this helps
