You can write the fraction 0.0003840 a number of ways.
0.0003840 = 0.003840/10 = 0.03840/100 = 0.3840/1000 = 3.840/10000
The one we're interested in is the last one, which has one non-zero digit to the left of the decimal point. The power of 10 in the denominator is the 4th power (the number of zeros is 4). 10^4 in the denominator is equivalent to multiplying by 10^(-4) in the numerator.
Expressed in scientific notation,
0.0003840 = 0.003840/10 = 0.03840/100 = 0.3840/1000 = 3.840/10000

Answer:
Step-by-step explanation:
The explicit form for an arithmetic sequence is:
where is the first term and [ted]d[/tex] is the common difference.
The given sequence is arithmetic because term-previous term is the same per each pair of term and previous term.
That is the following holds:
-4-3=-11-(-4)=-18-(-11)
All of these differences are equal to -7, the common difference.
So let's fill in the explicit form:
