What would be the third number in the sequence when you follow the given instruction?

a. Start at 4. Subtract 2 and multiply by 3.
4, -- , -- , _

b. Start at 5. Multiply by 2 and subtract 3.
5, -- , -- , _

c. Start at 8. Subtract 6, multiply by 3 and then add 2.
8, -- , -- , _

d. Start at 30. Add even consecutive numbers from 4.
30, -- , -- , _

a. Start at 4. Subtract 2 and multiply by 3.
4, (4-2) * 3 = 2 * 3 = 6, (6-2) * 3 = 4 * 3 = 12

Therefore, the third number in the sequence is 12.

b. Start at 5. Multiply by 2 and subtract 3.
5, (5*2) - 3 = 10 - 3 = 7, (7*2) - 3 = 14 - 3 = 11

Therefore, the third number in the sequence is 11.

c. Start at 8. Subtract 6, multiply by 3, and then add 2.
8, (8-6) * 3 + 2 = 2 * 3 + 2 = 6 + 2 = 8, (8-6) * 3 + 2 = 2 * 3 + 2 = 6 + 2 = 8

Therefore, the third number in the sequence is 8.

d. Start at 30. Add even consecutive numbers from 4.
30, 30 + 4 = 34, 34 + 6 = 40

Therefore, the third number in the sequence is 40.
