127 is the answer:
Given:
Series – 2, 3, 10, 29, 66…..
To find:
The next number in the series
Solution:
From the above-given series
If we take the numbers that are next to each other separately and subtract them we get,
3 – 2 = 1
10 – 3 = 7
29 – 10 = 19
66 – 29 = 37
Taking the numerals we get: 1, 7, 19, and 37
Now repeat the same step as above and subtract the number next to each other we get,
7 – 1 = 6
19 – 7 = 12
37 – 19 = 18
From the answers above we can observe a pattern, which is that they are multiples of 6:
6 x 1 = 6
6 x 2 = 12
6 x 3 = 18
Following this pattern, the next number when subtracted should give us a number, which when subtracted with 37, should give us 24, which is the next multiple in the series (6x 4 = 24). Therefore taking the missing number after one subtraction as X:
X – 37 = 24
X = 24 + 37
X = 61
Since we have the result of the second subtraction, To find the missing number, we must subtract 66 from the missing number to get 61. Therefore:
? – 66 = 61
? = 61 + 66
? = 127
Therefore the missing number is 127.
