The given number series is 1 8 36 ? 1100 7701
It follows a pattern that,
1
1 x 3 + 5 = 8
8 x 4 + 4 = 36
36 x 5 + 3 = 183
183 x 6 + 2 = 1100
1100 x 7 + 1 = 7701
Hence, the missing number in the given series is 183.
The pattern is *3,+2,*5,+4,*7,+6, . . . . .
So missing term is 623+6=629
Two series alternate here, with every third number following a different pattern.
In the main series, 4 is added to each number to arrive the next.
In alternate series, 5 is subtracted from each number t arrive the next number.
Here in the main series
3 + 4 = 7
7 + 4 = 11
11 + 4 = 15
15 + 4 = 19
In alternate series
24 - 5 = 19
19 - 5 = 14...
The pattern 'mpon' is repeated.
Clearly, the numerators of the fractions in the given sequence follow the series of 2, 3, 5, 7,... and the denominator follows 3, 9, 27, 81, 243, ...
Then, the next term in the given sequence is
.
The correct pattern is +1, -2, +3, -4, +5, . . . .
So,129 wrong and must be replaced by 123 + 5 = 128
Here "mba" is repeated
The given series follows a pattern of +19, x19, +17, x17, +15, x15,...
Here the number which is to be replaced in ? is
41310+15=41325.
ten = 3(number of letters)
nine = 4(number of letters)
sixty = 5(number of letters)
ninety = 6(number of letters)
seventy = 7(number of letters)
sixtysix = 8(number of letters)
ninetysix=96(number of letters)
Then, likwise choose the number which has 9 letters in its Spelling.
The given series follows the rule,
+(5x1), +(5x2), +(5x3), +(5x4), +(5x5),....
So starting from 37, 37 + 5 = 42, 42 + 10 = 52, 52 + 15 = 67, 67 + 20 = 87,...
So wrong number is 47 which is to be 42.
