Find the next two numbers
6,12,9,18, 15 ___ ____
6,12,9,18, 15, 30, 27, 54
Chelle forgot to subtract 3 from every other number.
6,12,9,18,15,30,60
6 x 2 = 12
9 x 2 = 18
15 x 2 = 30
30 x 2 = 60
6
12 = 6*2
9 = 12 - 3
18= 9*2
15 = 18 -3
30 = 15*2
27 = 30 - 3
so I say 30 then 27
Thanks, Ms. Sue!
Now I see!
To find the next two numbers in the sequence 6, 12, 9, 18, 15 ____, ____, we need to first identify the pattern or rule governing the sequence.
Looking at the given sequence, we can notice that the numbers alternate between being multiplied by 2 and divided by 2. Let's break it down:
6 × 2 = 12
12 ÷ 2 = 6
6 × 2 = 12
12 ÷ 2 = 6
So, from this observation, we can infer that the pattern is multiplying by 2, then dividing by 2, repeatedly.
Now, let's apply this pattern to find the next two numbers:
Starting from the last number, 15:
15 × 2 = 30
30 ÷ 2 = 15
Therefore, the next two numbers in the sequence are 30 and 15.
Hence, the complete sequence is: 6, 12, 9, 18, 15, 30, 15.
