To find the 10th term using the "divide by 2" rule, we start with the given sequence:
40, 20, 10
The rule states that each term is obtained by dividing the previous term by 2. Let's apply this rule to find the 10th term:
Term 1: 40
Term 2: 40 / 2 = 20
Term 3: 20 / 2 = 10
Term 4: 10 / 2 = 5
Term 5: 5 / 2 = 2.5
Term 6: 2.5 / 2 = 1.25
Term 7: 1.25 / 2 = 0.625
Term 8: 0.625 / 2 = 0.3125
Term 9: 0.3125 / 2 = 0.15625
Term 10: 0.15625 / 2 = 0.078125
Therefore, the 10th term of the sequence obtained using the "divide by 2" rule is approximately 0.078125.
