Identify the pattern and find the next number in the pattern. 0.8, 3.2 12.851.2

Savatey [412]

For this case we have the following sequence:
0.8
3.2
12.8
51.2
This sequence can be written as:
0.8 = 0.2 * 4 = 0.2 * 4 ^ 1
3.2 = 0.2 * 16 = 0.2 * 4 ^ 2
12.8 = 0.2 * 64 = 0.2 * 4 ^ 3
51.2 = 0.2 * 256 = 0.2 * 4 ^ 4
Therefore, we have that the generic expression for this case is:
an = 0.2 * 4 ^ n
Then, the next number is then:
a5 = 0.2 * 4 ^ 5 = 0.2 * 1024 = 204.8
answer
the next number in the pattern is 204.8

Alaina evaluated 1718+120 and got an answer of 1838. Which statement is true about her answer?

Setler79 [48]

Answer:

Her answer is not correct because the sum cannot be less than either addend.

The correct answer is $\frac{179}{180}$

Step-by-step explanation:

Given:

The expression to add is given as:

$\frac{17}{18}+\frac{1}{20}$

Alaina got the answer as $\frac{18}{38}$

Let us first try to add the fractions and arrive at the answer.

Taking LCD of 18 and 20, we get LCD = 180

Now, making denominators of each fraction equal to 180 and changing the numerators accordingly.

$=\frac{17\times 10}{18\times 10}+\frac{1\times 9}{20\times 9}\\=\frac{170}{180}+\frac{9}{180}\\=\frac{170+9}{180}=\frac{179}{180}$

Therefore, the result of Alaina is not correct because she got an answer which is less than the fraction $\frac{17}{18}$ . But when we add two fractions, the result must be greater than either of the addend.
