2,8,3,27,4,64,_________,125 find missing number? ?
Answers
Answer:
The missing number that replaces the blank is "5".
Step-by-step explanation:
Given number pattern: 2,8,3,27,4,64,____,125
To solve this question better, we need to first divide the numbers into a pair of 2 numbers and make 4 different number pairs.
Now, these number pairs include:
2, 8
3, 27
4, 64
__, 125
If we observe the first 3 pairs, there is the same relationship among the numbers of the pair.
The common relationship is that: The second number is the cube of the first number of the pair.
2³=8
3³=27
4³=64
Hence, the first number of the fourth pair will be the cubic root of the second number, thus ∛125 = 5.
Therefore, the number that replaces the blank is 5.
The complete pattern now will be 2,8,3,27,4,64,5,125.
