Number Series Questions

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.

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

Given number series -1, 244, 163, 190, 181, ?,

The pattern is as follows

1 + 243 = 244

244 - 81 = 163

163 + 27 = 190

190 - 9 = 181

181 + 3 = 184

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

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.)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 is bac/bac/bac/bac/bac/bac.
The pattern bac is repeated.

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.
