1. Count on or back in ones

We're counting forward or backward by 1.

(a) 5702, 5703, 5704, ____, ____, ____

- Pattern: increasing by 1
- Next numbers: 5705, 5706, 5707

✔ Answer: 5705, 5706, 5707

(b) 2745, 2744, 2743, ____, ____, ____

- Pattern: decreasing by 1
- Next numbers: 2742, 2741, 2740

✔ Answer: 2742, 2741, 2740

(c) 3105, 3104, ____, ____, 3101, ____

- Pattern: decreasing by 1
- So after 3104 → 3103, then 3102, then 3101 (given), then 3100

✔ Answer: 3103, 3102, 3100

2. Count on or back in tens

We're counting forward or backward by 10.

(a) 1631, 1621, 1611, ____, ____, ____

- Pattern: decreasing by 10
- 1611 - 10 = 1601
- 1601 - 10 = 1591
- 1591 - 10 = 1581

✔ Answer: 1601, 1591, 1581

(b) 9005, 9015, ____, ____, ____, 9055

- Pattern: increasing by 10
- 9015 + 10 = 9025
- 9025 + 10 = 9035
- 9035 + 10 = 9045
- Then 9055 (already given)

✔ Answer: 9025, 9035, 9045

(c) 7928, 7938, ____, ____, 7968, ____

- Pattern: increasing by 10
- 7938 + 10 = 7948
- 7948 + 10 = 7958
- Then 7968 (given)
- 7968 + 10 = 7978

✔ Answer: 7948, 7958, 7978

3. Count on or back in hundreds

We're counting forward or backward by 100.

(a) ____, 2662, 2562, ____, ____, 2262

- Look at known values: 2662 → 2562 → ? → ? → 2262
- Decreasing by 100 each time
- Before 2662: 2662 + 100 = 2762
- After 2562: 2562 - 100 = 2462
- Then 2362
- Then 2262 (given)

✔ Answer: 2762, 2462, 2362

(b) 6610, 6510, ____, ____, ____, 6110

- Decreasing by 100
- 6510 - 100 = 6410
- 6410 - 100 = 6310
- 6310 - 100 = 6210
- Then 6110 (given)

✔ Answer: 6410, 6310, 6210

(c) 8040, 8140, ____, ____, 8440, ____

- Increasing by 100
- 8140 + 100 = 8240
- 8240 + 100 = 8340
- Then 8440 (given)
- 8440 + 100 = 8540

✔ Answer: 8240, 8340, 8540

4. Count on or back in thousands

We're counting forward or backward by 1000.

(a) 2744, 3744, 4744, ____, ____, ____

- Increasing by 1000
- 4744 + 1000 = 5744
- 5744 + 1000 = 6744
- 6744 + 1000 = 7744

✔ Answer: 5744, 6744, 7744

(b) 7099, 6099, ____, ____, ____, 2099

- Decreasing by 1000
- 6099 - 1000 = 5099
- 5099 - 1000 = 4099
- 4099 - 1000 = 3099
- Then 2099 (given)

✔ Answer: 5099, 4099, 3099

(c) 9251, 8251, ____, ____, ____, 4251

- Decreasing by 1000
- 8251 - 1000 = 7251
