Answer 2

Answer:

the missing number is 215.

A is the correct option.

Step-by-step explanation:

We have been given that

5:124::6:___?

We will first find what operation we can do with 5 in order to get the number 124. The same operation will be applied on 6 to find the missing term.

The steps for finding 124 from 5 is shown below

• First we cube 5. $5^3=125$
• Now, we subtract 1 in 125. 125 - 1 = 124

Thus, we cube 6 and then subtract 1 to find the missing number.

$6^3=216$

216 - 1 = 215

Therefore, the missing number is 215.

A is the correct option.
