12576
2124
105
15
Explanation:
Second term = First term * 1 + 1 = 16
Third term = Second term * 2 + 2 = 34
Forth term = Third Term * 3 + 3 = 105
Fifth term = Forth term * 4 + 4 = 424
Sixth term = Fifth term * 5 + 5 =2125
Seventh term = Sixth term * 6 + 6 = 12576.
So 2124 is wrong.
Second term = First term * 1 + 1 = 16
Third term = Second term * 2 + 2 = 34
Forth term = Third Term * 3 + 3 = 105
Fifth term = Forth term * 4 + 4 = 424
Sixth term = Fifth term * 5 + 5 =2125
Seventh term = Sixth term * 6 + 6 = 12576.
So 2124 is wrong.

160
319
19
Explanation:
Double the number and add 1 to it.
So the series will be 4,9,39,79,159,319.
So 160 is wrong.
Double the number and add 1 to it.
So the series will be 4,9,39,79,159,319.
So 160 is wrong.
44433.32,36,41,61,86,122,171,235

171
61
Explanation:
Second term = First term + 22
Third term = Second term + 32
Fourth term = Third term + 42
Fifth term = Forth term + 52
Sixth term = Fifth term + 62
Seventh term = Sixth term + 72
So the third term should be 45 instead of 41.
Second term = First term + 22
Third term = Second term + 32
Fourth term = Third term + 42
Fifth term = Forth term + 52
Sixth term = Fifth term + 62
Seventh term = Sixth term + 72
So the third term should be 45 instead of 41.
44434.Find the wrong number in the given series.
3,8,15,24,34,48,63

Explanation:
The difference between consecutive terms are
respectively 5,7,9,11,13.
So 34 is the wrong number in the series.
The difference between consecutive terms are
respectively 5,7,9,11,13.
So 34 is the wrong number in the series.
44436.Find out the odd one out.

3
105
Explanation:
The pattern in the series is
1*3, 2*5, 3*7, 4*9, 5*11, 6*13, 7*15.
So the series will be 3,10,21,36,55,78,105.
So 70 is wrong term in the series.
The pattern in the series is
1*3, 2*5, 3*7, 4*9, 5*11, 6*13, 7*15.
So the series will be 3,10,21,36,55,78,105.
So 70 is wrong term in the series.
