Skip counting by 5's worksheet for practicing number patterns and arithmetic skills.

Problem: Skip Counting by 5's

The task is to fill in the missing numbers in each sequence by counting by 5's. Let's solve each part step by step.

---

#### Part 1:
The sequence is:
```
25 __ 35 40 __ __ 55 60 __ 70 75
__ 85 __ 95 100 __ 110 115 __ 125 __
```

- Top Row:
- Start with 25. Add 5 to get the next number: \( 25 + 5 = 30 \).
- Continue adding 5: \( 35 + 5 = 40 \), \( 40 + 5 = 45 \), \( 45 + 5 = 50 \), and so on.
- The completed row is:
\( 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75 \).

- Bottom Row:
- Start with 85. Add 5 to get the next number: \( 85 + 5 = 90 \).
- Continue adding 5: \( 95 + 5 = 100 \), \( 100 + 5 = 105 \), \( 105 + 5 = 110 \), and so on.
- The completed row is:
\( 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130 \).

Final Answer for Part 1:
```
25 30 35 40 45 50 55 60 65 70 75
80 85 90 95 100 105 110 115 120 125 130
```

#### Part 2:
The sequence is:
```
400 __ 410 415 __ 425 __ 435 440
__ 450 455 460 __ 470 475 __ 485
__ 495 500 __ 510 515 __ 525 530
__ __ 545 __ 555 560 __ __ 575
```

- Top Row:
- Start with 400. Add 5 to get the next number: \( 400 + 5 = 405 \).
- Continue adding 5: \( 410 + 5 = 415 \), \( 415 + 5 = 420 \), \( 425 + 5 = 430 \), and so on.
- The completed row is:
\( 400, 405, 410, 415, 420, 425, 430, 435, 440 \).

- Second Row:
- Start with 450. Add 5 to get the next number: \( 450 + 5 = 455 \).
- Continue adding 5: \( 460 + 5 = 465 \), \( 470 + 5 = 475 \), \( 480 + 5 = 485 \), and so on.
- The completed row is:
\( 445, 450, 455, 460, 465, 470, 475, 480, 485 \).

- Third Row:
- Start with 495. Add 5 to get the next number: \( 495 + 5 = 500 \).
- Continue adding 5: \( 500 + 5 = 505 \), \( 510 + 5 = 515 \), \( 520 + 5 = 525 \), and so on.
- The completed row is:
\( 490, 495, 500, 505, 510, 515, 520, 525, 530 \).

- Fourth Row:
- Start with 545. Add 5 to get the next number: \( 545 + 5 = 550 \).
- Continue adding 5: \( 555 + 5 = 560 \), \( 560 + 5 = 565 \), \( 570 + 5 = 575 \), and so on.
- The completed row is:
\( 540, 545, 550, 555, 560, 565, 570, 575, 580 \).

Final Answer for Part 2:
```
400 405 410 415 420 425 430 435 440
445 450 455 460 465 470 475 480 485
490 495 500 505 510 515 520 525 530
540 545 550 555 560 565 570 575 580
```

#### Part 3:
The sequence is:
```
__ 875 __ __ 890 __ 900 905 __
915 920 __ 930 __ 940 945 __ 955
960 965 __ 975 980 __ 990 __ 1,000
```

- Top Row:
- Start with 875. Subtract 5 to find the previous number: \( 875 - 5 = 870 \).
- Continue adding 5: \( 875 + 5 = 880 \), \( 880 + 5 = 885 \), \( 890 + 5 = 895 \), and so on.
- The completed row is:
\( 870, 875, 880, 885, 890, 895, 900, 905, 910 \).

- Second Row:
- Start with 915. Subtract 5 to find the previous number: \( 915 - 5 = 910 \).
- Continue adding 5: \( 920 + 5 = 925 \), \( 930 + 5 = 935 \), \( 940 + 5 = 945 \), and so on.
- The completed row is:
\( 915, 920, 925, 930, 935, 940, 945, 950, 955 \).

- Third Row:
- Start with 960. Subtract 5 to find the previous number: \( 960 - 5 = 955 \).
- Continue adding 5: \( 965 + 5 = 970 \), \( 975 + 5 = 980 \), \( 985 + 5 = 990 \), and so on.
- The completed row is:
\( 960, 965, 970, 975, 980, 985, 990, 995, 1000 \).

Final Answer for Part 3:
```
870 875 880 885 890 895 900 905 910
915 920 925 930 935 940 945 950 955
960 965 970 975 980 985 990 995 1000
