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
Correct Answer: 92
Explanation:
The pattern is + 1*1,+ 2*2, +3*3, + 4*4,+ 5*5,+ 6*6, . . . . . . .
So missing term is 56+36=92
Correct Answer: 256
Explanation:
The given number series is 2, 16, 3, 81, 4, ?
2
2^4 = 16
3
3^4 = 81
4
4^4 = 256
Hence, the next number is 256.
Correct Answer: 375
Explanation:
The given number series is 200, 200, 100, 300, 75, ?
It follows a pattern that,
200
200 x 1 = 200
200 / 2 = 100
100 x 3 = 300
300 / 4 = 75
75 x 5 = 375
Hence, the next number in the given number sequence is 375.
Correct Answer: 15O16
Explanation:
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
Correct Answer: 78

The pattern is 2x32=64, 3x24=72, 4x19=76
The next number = 5x15.6=78
Correct Answer: 40

So wrong number is 40 which is to be 51.
