Question
In each of the following number series, one term is wrong. Find the wrong term. 3, 5, 8, 13, 21, 33, 55
Solution
ATQ, This looks like a Fibonacci-type series (each term = sum of previous two): 3, 5 Next should be 3 + 5 = 8 Next: 5 + 8 = 13 Next: 8 + 13 = 21 Next: 13 + 21 = 34 Next: 21 + 34 = 55 So the correct series should be: 3, 5, 8, 13, 21, 34, 55 Given series has 33 instead of 34. Therefore, 33 is the wrong term.
