Question

Given the sequence: 128, 32, 8, 2, ½, …

State the rule verbally. In other words, state how you would tell someone the sequence without just listing the numbers in the sequence.




Write the recursive rule for the sequence.




Write the explicit rule for the sequence.

please help me :')

Answer 1

You divide by 4.
Recursive rule: an=r•an-1
An=0.125(4) is the answer
this is a geometric rule because your dividing

Explicit rule: 128+4(n-1)
