Answer 1

$\huge\red{ANSWER}$

________________

1▪ 3 ,15 ,4 ,16 ,5 ,17 ,6 , ? , 7

U can see here its 3 then 15 and 4 then 16 then its 5 then 17 , 6 then (Trick :- 15 , 16 , 17 so off course next one will be ....18 ) SONEXT ONE OR MISSING ONE IS 18 and then its 7 (given )

2▪2 , 6 , 12 , 20 , 30

2 , 6 (difference of 4 numbers)

6, 12 (difference of 6 numbers)

12 , 20 (difference of 8 numbers )

12 , 30 (difference of 10 number )

TRICK :- its difference of 4 then 6 , 8 , 10 Now it will be 12 (2 is added to previous number , as 4+2=6 +2=8+2=10+2=12)

Therefore the missing number is 42

2 , 6 , 12 , 20 , 30 , 42

3▪ 68 , 81 , 96 , ? , 132

here subtract 68 from 81 so there is a difference of 13 then subtract 81 from 96 difference of 15 So its simple add 17 to 96
it becomes 113 then add 19 to 113 we get 132

4▪ 1 , 1 , 6 , 6 , 11 , 11 , 16 , ? ,?

So i think here the missing words will be 16 and 21

Answer 2

Hello mate the answers to your question are as follows:-

Series 1

3 , 15 , 4, 16 , 5, 17, 6, ? , 7

In this series notice that for every odd term in the series the series is like:-

3..............4...........5.........6........7

You can easily make out that they are increasing by 1.

And the even terms

15............16.............17............?

The series is also increasing by 1.

So the ? sign will be 17+1 which is 18.

Answer:- 18

Series 2

Just notice the difference between the succeeding terms

2, 6,  12, 20,30

6-2 is 4.

12-6 is 6

20-12 is 8.

30-20=10

So their differences are in increasing by 2 for each term.

This means that ?-30 will be 2 more than 30-20

We can write it down as a linear equation:-

thus ?-30-2=30-20

Thus :- ?-30+2=10

?=10+30-2

?=40+2

Thus the missing number is 42.

Answer:-42

Series 3

Same type of series.

68,81,96,?,132

81-68=13

96-81=15

Thus

?-96 should be 17

It is because their differences are increasing by 2.

Hence ?=96+17

=113.

If we add 19 to 113 we will get 132.

Thus the answer is correct.

Answer:-113

Series 4

1,1,6,6,11,16??

After 1 ..........1.........then the number is getting increased by 5

so then 1.......1........6.........then again the same last term that is 6

After that it is again increasing by 5.

So: 1.....1..........6......6...............11......11.................16.....?...............?

What will be the next two terms?

Well next term is equal to 16.

Then the succeeding term will be : 16+5 which is 21

Hence your answer is 16 then 21.

Answer:-16,21

Hope it helps you mate.
