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
Clearly, alternatively we add and subtract 10% of a term to obtain the next term of the series.
Thus, 10000 + (10% of 10000)= 11000;
11000 - (10% of 11000) = 9900;
9900 + (10% of 9900) = 10890;
10890 - (10% of 10890) = 9801.
9801 + (10% of 9801) = 9801+980 = 10781.
So, missing term = 10890- (10% of 10890)= 9801.
First letter moves 6 steps forward. Second letter moves 6 steps backward.
Here the number follows the given rule
But 28 has been given in problem series.
so 28 is wrong number.
Here 2nd number = (1st number x 1 )+1
3rd number = (2nd number x 2 +2)
4th number = (3rd number x 3 )+3 and so on..
Therefore, 5th number = (4th number x 4) +4 =57 x 4 + 4 =232.
The given sequence a combination of two series:
I)Z, W, T, Q, ? and II)S, O, K, G, ?
The pattern I is
Z - 3 = W
W - 3 = T
T - 3 = Q
Q - 3 = N
The pattern in II is
S - 4 = O
O - 4 = K
K - 4 = G
G - 4 = C
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 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 correct pattern is -192, -96, -48, -24, -12, -6
So, 48 is wrong and must be replaced by (92 - 48) = 44
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
