Find out the wrong number in the given sequence of numbers.
Answer: Option D
Explanation:
The numbers are 13, 23, 33, 43 etc. So, 124 is wrong;
it must have been 53 i.e., 125.
Answer: Option A
Terms at odd places are 5, 6, 7, 8 etc. and each term at even place is 16.
So, 9 is wrong.
The differences between two successive terms from the beginning are 7, 5, 7, 5, 7, 5.
So, 40 is wrong.
The numbers are 7 x 8, 8 x 9, 9 x 10, 10 x 11, 11 x 12, 12 x 13.
So, 150 is wrong.
Answer: Option B
The terms are alternatively multiplied by 1.5 and divided by 3. However, 18.5 does not satisfy it.
