See the graph and found that the given number in the series with specific pattern.
From the given graph , we can see that the increasing order of series as -
First term = 2
Second term = First term + 1 = 2 + 1 = 3 ,
Third term = Second term x 2 = 3 x 2 = 6 ,
Fourth term = Third term + 1 = 6 + 1 = 7 ,
Fifth term = Fourth term x 2 = 7 x 2 = 14 ,
Sixth term = Fifth term + 1 = 14 + 1 = 15 ,
Seventh term = Sixth term x 2 = 15 x 2 = 30
? Seventh term( ? ) = 30

See the below image and you will find a pattern in which numbers are getting added for next number in the given series.
From the given figure , we get the value of sixth term ( ? ) = 69

From the above given series , we have
First term + 350 = Second term
? 156 + 350 = 506
Second term + 550 = third term
? 506 + 550 = ? ? ? = 1056
From the given figure , we get the value of third term ( ? ) = 1056
Third term + 550 = Fourth term
? 1056 + 750 = 1806

The order of above series is given as
First term = 7
Second term = ( First term x 2 ) +9
? Second term = ( 7 x 2 ) + 9 = 14 + 9 = 23
Third term = ( Second term x 2 ) +11
? Third term = ( 23 x 2 ) + 11 = 46 + 11 = 58 is wrong , 57 should be Third term because ( 23 × 2 ) + 11 = 57 .
Similarly we can find all others terms also.
Fourth term = ( Third term x 2 ) +13
? Fourth term = ( 57 x 2 ) +13
Fifth term = ( Fourth term x 2 ) +15
? Fifth term = ( 127 × 2 ) + 15 = 269
Sixth term = ( Fifth term x 2 ) +17
? Sixth term = ( 269 × 2 ) + 17 = 555

As per the details in the question the series is in the form of
First term = 1
Second term = ( First term × Variable ) + Variable
? Second term = ( 1 × 1 ) + 1 = 2
Third term = ( First term × Variable ) + Variable
? Third term = ( 2 × 2 ) + 2 = 8 , So 8 is wrong. we get 6 as Third term.
Similarly , we can find the all terms also.
Fourth term = ( 6 × 3 ) + 3 = 21
Fifth term = ( 21 × 4 ) + 4 = 88
Sixth term = ( 88 × 5 ) + 5 = 445

From given figure , it is clear that the increasing order of series given as -
First term = 0
Second term = First term + 5
? Second term = 0 + 5 = 5
Third term = Second term + 55
? Third term = 5 + 55 = 60
Similarly , we can find all others terms also.
Fourth term = Third term + 555
? Fourth term = 60 + 555 = 615
Fifth term = Fourth term + 5555
? Fifth term = 615 + 5555 = ?
? Fifth term ( ? ) = 6170

24 ÷ 4 + 6 - 3 x 4 = 6 + 6 - 12 = 0

The pattern of the number series is as given below ;
8 + 2 = 10
10 + 8 (= 2 x 3 + 2) = 18
18 + 26(= 3 x 8 + 2) = 44
44 + 80 (= 3 x 26 + 2) = 124
124 + 424 (= 3 x 80 + 2) = 366

The pattern of the number series is as given below:

13 + 1 x 12 = 13 + 12 = 25
25 + 3 x 12 = 25 + 36 = 61
61 + 5 x 12 = 61 + 60 = 121
121 + 7 x 12 = 121 + 84 = 205
205 + 9 x 12 = 205 + 108 313
