Answer:

The given sequence is an arithmetic sequence.

Step-by-step explanation:

Given sequence is:

7, 10, 13, 16, ...

Here

a_1 = 7\\a_2 = 10\\a_3 = 13\\a_4 = 16

In order for a sequence to be an arithmetic sequence the common difference between the consecutive terms of the sequence should be same. Common difference is denoted by d.

So,

d = a_2 - a_1 = 10-7 = 3\\d = a_3 - a_2 = 13-10 = 3\\d = a_4-a_3 = 16-13 = 3

As we can see that the common difference is same for consecutive terms.

The given sequence is an arithmetic sequence.

Round 8,937.2546 to the nearest<br> hundred.
xeze [42]

Answer:

8,900

Step-by-step explanation:

Given Number: 8,937.2546

Determine the two consecutive multiples of 100 that bracket 8,937.2546

8,937.2546 is between 8,900 and 9,000

8,950 is the midpoint between 8,900 and 9,000

As illustrated on the number line, 8,937.2546 is less than the midpoint (8,950)

Therefore, 8,937.2546 rounded to the nearest hundred = 8,900
