Answer: $a_n=2(5)^{n-2}$

<u>Step-by-step explanation:</u>

The explicit rule for a geometric sequence is: $a_n=a_1(r)^{n-1}\quad \text{where}\ a_1\ \text{is the first term and r is the ratio}$

The information provided is: a₁ = $\dfrac{2}{5}$ and r = 5

$a_n=\dfrac{2}{5}(5)^{n - 1}\\\\.\quad = 2(5)^{n-2}$

Answer:

Option B

Step-by-step explanation:

Given the following question:

In order to find the answer, we need to convert the scientific notation into standard notation and then simplify by subtracting the decimals. Then we convert the standard notation back into scientific notation.

$0.0007 - (4.9\times 10^{-7} )$
$4.9\times10^{-7} =0.00000049$
$0.0007-0.00000049$
$0.0007-0.00000049=0.00069951$
$=0.00069951$
$0.00069951=6.9951 \times10^{-7}$
$=6.9951 \times10^{-7}$

Your answer is "6.9951 × 10^-7" or option B.

Hope this helps.
