To find the missing numbers in the sequence 283,280,,,271,,265,,259,,253,, you can use the following method. |
|
3 |
Step |
The first number is |
283 |
4 |
Step |
The second number is |
280 |
5 |
Step |
The difference between 283 and 280 is |
283 - 280 = 3 |
6 |
Step |
The difference between 280 and the next number is also |
3 |
7 |
Step |
So the next number is |
280 - 3 = 277 |
8 |
Step |
The difference between 277 and the next number is also |
3 |
9 |
Step |
So the next number is |
277 - 3 = 274 |
10 |
Step |
The difference between 274 and the next number is also |
3 |
11 |
Step |
So the next number is |
274 - 3 = 271 |
12 |
Step |
The difference between 271 and the next number is also |
3 |
13 |
Step |
So the next number is |
271 - 3 = 268 |
14 |
Step |
The difference between 268 and the next number is also |
3 |
15 |
Step |
So the next number is |
268 - 3 = 265 |
16 |
Step |
The difference between 265 and the next number is also |
3 |
17 |
Step |
So the next number is |
265 - 3 = 262 |
18 |
Step |
The difference between 262 and the next number is also |
3 |
19 |
Step |
So the next number is |
262 - 3 = 259 |
20 |
Step |
The difference between 259 and the next number is also |
3 |
21 |
Step |
So the next number is |
259 - 3 = 256 |
22 |
Step |
The difference between 256 and the next number is also |
3 |
23 |
Step |
So the next number is |
256 - 3 = 253 |
24 |
Step |
The difference between 253 and the next number is also |
3 |
25 |
Step |
So the next number is |
253 - 3 = 250 |
26 |
Step |
So the missing numbers are 277,274,268 262,256, and 250, and the complete sequence is 283,280,277,274,271,268,265,262,259,256,253,250. |
