In following question, a number series is given with one term missing. Choose correct alternative

1, ?, 5, 10, 20, 40, 80

1, ?, 5, 10, 20, 40, 80

Next number is sum of all previous numbers.

1st Term : 1

2nd Term: 4

3rd Term: 1+4 =5

4th Term: 1+4+5= 10

5th Term: 1+4+5+10=20 and so on.....

In following questions, one term in number series is incorrect.

Find out the incorrect number

6, 14, 30, 64, 126

Find out the incorrect number

6, 14, 30, 64, 126

Each term is multiplied by 2 and then increased by 2 to obtain the next term.

So, 64 is wrong and must be replaced by (30 * 2 + 2) i.e. 62..
