I just found this random q.
Q. find out the wrong term in the given sequence of numbers
52,51,48,43,34,27,16
Explain your answer in detail
Answers
52 -51 = 1
51 -48 = 3
48-43 = 5
43 -34 = 9 ( it should be 7)
So 34 should be 36
36 -27 = 9
27 -16 = 11
✌✌So 34 is wrong no✌✌
Answer:
The odd one out in the following sequence is 34
Correct one should be 36 .
Step-by-step explanation:
I will start from the end .
Let us rotate the given data :
16 , 27 , 34 , 43 , 48 , 51 , 52 .
We notice that as we are approaching towards the right end the difference among the numbers are decreasing .
Hence the main logic behind the sequence must involve subtraction .
By subtraction we will come to common difference logic .
Let us find the increase / decrease and rate of such increase / decrease in the common difference .
To start with , we will name the variables like a1 , a2 , ..... and hence we are required to depict the logic in a2 - a1 , a3 - a2 , .. and so on .
27 - 16 = 11
34 - 27 = 7
43 - 34 = 9
48 - 43 = 5
51 - 48 = 3
52 - 51 = 1
Logically the bolded part is wrong .
Here the difference should be 9 and 7 but they are 7 and 9 .
So if we change the number 34 , then the problem is solved .
Change 34 to 36 , then 36 - 27 = 9 and 43 - 36 = 7 .
Basically the common difference of the sequence is itself an A,P .
