Number Series Questions

The correct pattern is -192, -96, -48, -24, -12, -6
So, 48 is wrong and must be replaced by (92 - 48) = 44

The given sequence is a combination of two series:
i)0, 3, 8, 15, 24, 35
ii)2, 5, 10, 18, 26
The pattern in both i, ii is +3, +5, +7, . . . .
So, in ii) 18 is wrong and must be replaced by (10 + 7) = 17

First letter moves 6 steps forward. Second letter moves 6 steps backward.

1.)D + 12 = P
P + 12 = B
B + 12 = N
2.)H + 12 = T
T + 12 = F
F + 12 = R
3.)L + 12 = X
X + 12 = J
J + 12 = V

The given series consists of squares of consecutive prime numbers
2*2, 3*3, 5*5,  . . . . , 11*11, 13*13, 17*17

In the given series,

 2nd term = 1st term -82 = 888-82=440  

 3rd term = 2nd term -82=440-82=216  

and so on...

Here 6th term = 5th term -82=48-82=20

 Therefore, 22 is wrong.

The given sequence is a combination of two series:
i.)Y,T, O and ii.)B, G, ?
i. consists of 2nd, 7th, 12th letters from end of English alphabet,while
ii. consists of 2nd, 7th, 12th letters from beginning of English alphabet
So, the missing letter in ii.) is the 12th letter from the beginning of English alphabet,which is L.

The series rtus/rtus/rtus/rtus. Thus, the pattern 'rtus' is repeated.
