Question

15: 215::16:342::26:511:: 65:?
what will be in the place of question mark ​

Answer 1

Answer:

1330

Step-by-step explanation:

in 15:215,

5 + 1 = 6

$6^{3}$ = 216

216 - 1 = 215

in 16:342

6 + 1 = 7

$7^{3}$ = 343

343 - 1 = 342

therefore,

finally,in 65:?

6 + 5 = 11

$11^3$ = 1331

1331 - 1 = 1330
