What is the next number of the following sequence 6,39,94,171,270,.....

Ashfaque Hussain   11 years AGO

39-6 = 33
94-39 = 55
171-94 = 77
270-171 = 99
Difference b/w two terms increasing by 22
So, next difference b/w two no. 99+22=121
Next number = 270+121 = 391

Like? Yes (19) | No (2)

susmit   11 years AGO

1st order differences are 33, 55, 77, 99.
2nd order differences are 22, 22, 22.
So the fifth 1st order difference is 99 + 22 = 121.
Hence the required number is 270 + 121 = 391.
Hence option no.(6)

Dharmendra Singh   11 years AGO

ans. 6)391
Explanation:
there's difference in odd multiple of 11
39-6=33=11*3
94-39=55=11*5
171-94=77=11*7
270-171=99=11*9
next will maintain difference 11*11
so 391-270=121=11*11 :)

Dharmendra Kumar Rajak   11 years AGO

Given sequence is 6,39,94,171,270,.....
We will expand it as follows
39-6=33 =>6+33=39;
94-39=55 =>39+55=94;
171-94=77 =>94+77=171;
270-171=99 =>171+99=270;
Similarly =>270+121=391;
So option (6) is correct.

Like? Yes (1) | No   

Dipak Shaw   11 years AGO

answer is 6)391
6+33=94
94+55=171
Starting with d addition of 33 in the first no.,then
in next no. addition of 22 more as compare to previous addition. i.e.addition of 33+22=55
And this process will continue
so the series will be
6+33 = 39
39+55 =94
94+77 =171
171+99=270
270+121 =391

Like? Yes (1) | No   

Prakash kumar   11 years AGO

difference between the terms are 33, 55, 77, 99
And the difference between these terms is 22
therefore 99+22= 121
so next term will be 270+121 = 391

Raisul Alam   11 years AGO

The diffrence between two consequtive numbers are 33(39-6),55(94-39),77(171-94),99(270-171)..So the diffrences are 33(11*3),55(11*5),77(11*7),99(11*9) and the next diffrence will be 11*11 hence 121. So the next number will be 270+121=391
