patterns with fractions
write a rule for the sequence.then,find the unknown number
how do you do this?ill give you an example...1/2, 2/3, 1, 1 1/6.it says,think:the pattern is increasing.add 1/6 to find the next term.here is a problem.... 1 3/8, 1 3/4, 2 1/8, 2 7/8 rule:
I don't know what to do please help
thank you
anbody there
PLEASE ANSWER!!!???!!!
Try converting to fractions. Then you have
11/8 14/8 17/8 23/8
I think the last one should be 2 1/2, since you added 3/8 the first two times.
If it really is 2 7/8, ya got me.
Or, it could be that you just missed a term of 2 1/2 in between 2 1/8 and 2 7/8.
thank you Steve
:-)
ill wit for more answers
whoever answers me again It should be..... 1 3/8, 1 3/4, 2 1/8, __, 2 7/8
Oh, well, why didn't you say so? I gave you the answer above. Read things carefully, ok? Stop sittin' around waiting for someone to hold your hand.
I need help
To find a rule for the given sequence and determine the unknown number, we need to observe the pattern and identify how the numbers are changing.
Let's analyze the sequence: 1 3/8, 1 3/4, 2 1/8, 2 7/8
Step 1: Look for any consistent change between consecutive terms:
- Notice that the whole numbers are increasing by 1 (1, 2), but the fractional part is not changing consistently.
Step 2: Focus on the fractional part:
- Look at the fractions in the sequence: 3/8, 3/4, 1/8, 7/8
- Observe how the numerators are changing: 3, 3, -7
- Notice that the denominators are the same: 8 in each fraction.
Step 3: Identify the pattern and determine the rule:
- The whole numbers in the sequence are increasing by 1 (1, 2).
- The numerators in the fractions are following a pattern: 3, 3, -7.
- Since the denominators remain the same, the pattern is only in the numerators.
- The rule for the numerator pattern seems to be adding 0, then adding 0, then subtracting 10.
- To summarize the rule for the sequence: Add 0, Add 0, Subtract 10.
Step 4: Apply the rule to find the unknown number:
- Using the rule, we increase the whole number by 1 (2) and follow the pattern for the numerator.
- Start with the numerator from the last fraction (2) and follow the pattern: add 0.
- 2 + 0 = 2.
- Therefore, the unknown number in the sequence is 2.
So, the rule for the sequence is: Increase the whole number by 1 and add 0 to the numerator. The unknown number in this specific sequence is 2.
