Answer 2

The missing number (?) = 799

Step-by-step explanation:

The given series:

1, 8, 15, 64, 113, 456, ?​

To find, the missing number in the given series(?) = ?

The patten follow:

Previous number + $7^{1}$, Previous number + $7^{1}$, Previous number + $7^{2}$, Previous number + $7^{2}$, Previous number + $7^{3}$, Previous number + $7^{3}$, ....

8 = 1 + $7^{1}$ = 1 + 7 = 8

15 = 8 + $7^{1}$ = 8 + 7 = 15

64 = 15 + $7^{2}$ = 15 + 49 = 64

113 = 64 + $7^{2}$ = 64 + 49 = 113

456 = 113 + $7^{3}$ = 113 + 343 = 456

Similarly,

? = 456 + $7^{3}$ = 456 + 343 = 799

∴ The missing number (?) = 799
