Which answer describes the pattern in this sequence?
1,2,1/2,1/4,
add 1/2
add , 1 half
subtract 1
multiply by 2
multiply by 1/2
To determine the pattern in the sequence, let's analyze the given sequence step by step:
1, 2, 1/2, 1/4
Observing the progression, we can notice that each term is obtained by applying the following operations:
1st term: Starting term or first number
2nd term: Add 1 to the previous term (1 + 1 = 2)
3rd term: Divide the previous term by 2 (2/2 = 1/2)
4th term: Divide the previous term by 2 again (1/2 ÷ 2 = 1/4)
Therefore, the pattern in this sequence is that each term is obtained by dividing the previous term by 2.
