1. **State the problem:** We are asked to fill in the blanks in sequences and multiply numbers by 8. 2. **Fill in the blanks:** - (1) The sequence is 32, 40, 48. These numbers increase by 8 each time. - (2) The sequence is 40, 48, 56. These numbers also increase by 8 each time. - (3) The sequence is 48, 56, 64. Again, increasing by 8 each time. 3. **Multiply by 8:** - (1) $2 \times 8 = 16$ - (2) $3 \times 8 = 24$ - (3) $5 \times 8 = 40$ - (4) $7 \times 8 = 56$ - (5) $9 \times 8 = 72$ - (6) $8 \times 8 = 64$ - (7) $4 \times 8 = 32$ - (8) $6 \times 8 = 48$ - (9) $3 \times 8 = 24$ - (10) $7 \times 8 = 56$ - (11) $6 \times 8 = 48$ - (12) $1 \times 8 = 8$ - (13) $8 \times 8 = 64$ - (14) $5 \times 8 = 40$ - (15) $0 \times 8 = 0$ - (16) $4 \times 8 = 32$ **Final answers:** - Sequences: (1) 32, 40, 48; (2) 40, 48, 56; (3) 48, 56, 64 - Multiplications: 16, 24, 40, 56, 72, 64, 32, 48, 24, 56, 48, 8, 64, 40, 0, 32 This completes the problem.
