The pattern is 2x32=64, 3x24=72, 4x19=76
The next number = 5x15.6=78
The first digit is formed by adding the numbers which are the results of powers of 2 increased by one and second letter is the corresponding alphabet to that number...last number is the next number to the first one...therefore
15=7+8 (i.e. 2^3)
O is corresponding alphabet to 15
and 16 comes after 15
The first letter moves two steps forward. The last letter moves one steps backward. The number series runs as follows :
1 x 1 + 1 = 2
2 x 2 + 2 = 6
6 x 3 + 3 = 21
21 x 4 + 4 = 88.
The letters move 1, 2, 3, ... steps forward.
The numbers increase by + 3, + 5, + 7, + 9....
The sequence is 13*13,12*12,11*11,10*10,9*9,8*8, . . . . . .
So,85 is wrong term and must be replaced by 9*81
The pattern is + 1*1,+ 2*2, +3*3, + 4*4,+ 5*5,+ 6*6, . . . . . . .
So missing term is 56+36=92
The given series follows the rule,
+(11x1), +(11x3), +(11x5), +(11x7), +(11x9),....
So starting from 7, 7 + 11 = 18, 18 + 33 = 51, 51 + 55 = 106, ...
So wrong number is 40 which is to be 51.
the pattern is +6,+9,+12,+15
the missing term is 21+12=33
The first letters of the terms are alternate.
The sequence followed by the numbers is +2, +3, +4,....
The last letter of is three steps ahead of the last letter of the preceding term.
The given series is 118, 166, 190, 202, 208, ?
118
118 + 48 = 166
166 + 24 = 190
190 + 12 = 202
202 + 6 = 208
208 + 3 = 211
