Question

16, 06, 68, 88, ?, 98.

What is the ' ? ' ?

​

Answer 1

128

Explanation:

1. (16-06) =10

2. (88-68) =20

3. (?-98) = 30

BCAUSE

d = 10

let us assume

? =x

therefore

x-98= 30

x=98 + 30

x = 128

hence ? =128

hope it is HELPFULL

Answer 2

Answer:

Approach1: rotate the page on which you wrote down the series and you will observe a simple sequence …the obvious ans to which is 87 but on rotating back the page to it's original orientation , you notice strange thing - letter 'L' is coming next to 8 which gives the final ans as L8

Series: 16, 06,68,88,?,98

Ans: 16, 06, 68, 88, L8, 98. (I don't personally think it's correct)

Approach 2:

Count number of circles in each number ie (16) has 1 circle ( notice the circle in 6 ) and so on

Therefore the series is simplified to a another level

Original series : 16, 06, 68, 88, ? ,98

Simplified :. 1, 2,3,4,?,3 circles

Logic : I'm considering the fact that repetition is allowed as its mostly never mentioned in question and hence 4 circles will come in question mark place

-> 4 circles ie 88 can be one possibility

Ans: 16, 06, 68, 88, 88, 98
