Tell whether the sequence is arithmetic. Justify your answer. If the sequence is arithmetic, write a recursive

navik [9.2K]

Answer:

The explicit formula

$a_n = 3 +0.25 (n-1)$

The recursive formula

$a_1 = 3$ for $n=1$

$a_n = a_ {(n-1)} +0.25$ if $n>1$

Step-by-step explanation:

If a sequence is arithmetical then the difference between any of its consecutive terms will be constant

3, 3.25, 3.5, 3.75,

$3.25-3 = 0.25\\\\3.5-3.25 = 0.25\\\\3.75 -3.5 = 0.25$

The difference between the consecutive terms remains constant so the sequence is arithmetic.

The explicit formula for an arithmetic sequence is:

$a_n = a_1 + d (n-1)$

Where d is the constant difference between the terms.

$d = 0.25$

$a_1$ is the first term of the sequence.

$a_1 = 3$

$a_n = 3 +0.25 (n-1)$

Finally, the recursive formula is:

$a_1 = 3\\\\a_n = a_ {(n-1)} +0.25$

jolli1 [7]

Answer:

6.21 times more

Step-by-step explanation:

Assuming 2.04 x 10^11 was only a typo

you would need to first equal the powers of 10

so 20.4 x 10^10 and 3.28 x 10^10

now that they have the same powers

$\frac{20.4 * 10^{10}}{3.28 * 10^{10}} = \frac{20.4}{3.28} = 6.219512...$

if it's asking for how many times i would approximate it to 6.21 times more

The surface area of the prism is ______ square units. All measurements in the image below are in units. (Input whole number only

White raven [17]

To find the area of a triangle, use 1/2 x b x h. 3 x 4 = 12 1/2 of 12 = 6

There are two triangles, each of these are 6 6 x 2 = 12

The bottom shape is 3.5 x 3 3.5 x 3 = 10.5

The front shape is 3.5 x 5 3.5 x 5 = 17.5

The back shape is 3.5 x 4 3.5 x 4 = 14

Add them all together: 14 + 17.5 + 10.5 + 12 = 54

Your answer is 54!
