The series follows a pattern that,
-92, +82, -72, +62, -52
Given series follows Cubes on Prime Numbers
i.e but is 1331
so 1381 is wrong
In the first step, one letter from the beginning and one from the end of a term are removed to give the next term . In the second step, two letters from the beginning of the term are removed. These two steps are repeated alternatively
The correct pattern is -192, -96, -48, -24, -12, -6
So, 48 is wrong and must be replaced by (92 - 48) = 44
The given series follows a pattern that,
19 x 19 x 19 = 6859
18 x 18 x 18 = 5832
17 x 17 x 17 = 4913
16 x 16 x 16 = 4096
15 x 15 x 15 = 3375
So, the missing number in the given series = 4913
The given series consists of squares of consecutive prime numbers
2*2, 3*3, 5*5, . . . . , 11*11, 13*13, 17*17
The pattern is -95, -85, -75, -65, . . . .
T - 2 = R
R - 2 = P
P - 2 = N
N - 2 = L
L - 2 = J
J - 2 = H
There is a gap of 4 letters between the first and second, second and third letters of each term, and also between the last letter of the term and first letter of next term
The series is bac/bac/bac/bac/bac/bac.
The pattern bac is repeated.
