Question

1, 11, 35, 79, 149, 251,
Find the next number in each sequence, using successive differences

Answer 1

Answer:

391 is the answer.

Step-by-step explanation:

the difference between 11 to 35 is = 24

" " " 35 to 79 = 44

" " " 79 to 149 = 70

" " " 149 to 251 = 102

Now, the no. is = 24 , 44 , 70 , 102

* The difference between 24 to 44 = 20

" " " 44 to 70 = 26

" " " 70 to 102 = 32

Now, the sequence is 20 , 26, 32

* The difference between 20 to 26 = 6

" " " 26 to 32 = 6

Therefore, the 6 added to the 32 then the next no will come.

* 32 + 6 = 38

Or, 32 added to the 102 then next no will come.

* 102 + 38 = 140

Or, 140 is added to 251 then the Our final sequence will come.

=). 251 + 140 = 391 Answer.
