Question

3,19,103,439,1381,_ give reason bro​

Answer 1

The given series are:

3, 19, 103, 439, 1381, ____

We have to find, the value of missing number (?) is:

Solution:

The pattern follow:

(Previous number × 6) + $1^{3}$, (Previous number × 5) + $2^{3}$, (Previous number × 4) + $3^{3}$, (Previous number × 3) + $4^{3}$, (Previous number × 2) + $5^{3}$, .....

19 = (3 × 6) + $1^{3}$

= 18 + 1 = 19

103 = (19 × 5) + $2^{3}$

= 95 + 8 = 103

439 = (103 × 4) + $3^{3}$

= 412 + 27 = 439

1381 = (439 × 3) + $4^{3}$

= 1317 + 64 = 1381

Similarly,

? = (1381 × 2) + $5^{3}$

= 2762 + 125 = 2887

∴ Missing number (?) = 2887

Thus, the value of "missing number (?) is  2887".
