Complete the sequence.<br><br>37.25​, 35.5​, 33.75​, __, __.
Leviafan [203]

Answer:

37.25​, 35.5​, 33.75​, <u>32</u>, <u>30.25</u>.

Step-by-step explanation:

Subtract the first term from the second term:

35.5 - 37.25 = -1.75

Subtract the second term from the third term:

35.5 - 33.75 = -1.75

The common difference is -1.75.

To find each subsequent term, add the common difference to the current term.

33.75 + (-1.75) = 32

32 + (-1.75) = 30.25

Answer:

37.25​, 35.5​, 33.75​, <u>32</u>, <u>30.25</u>.

Explain how finding 4 times 384 can help you find 4 times 5,384
Lubov Fominskaja [6]

5384=5000+384

4 * 5384 = 4(5000+384) = 4 * 5000 + 4 * 384

4 * 5000 = 20000

20000 + 4 * 384

So to find 5384 * 4, you add 20000 to 4*384. Less calculations
