Answer 2

Answer:

The required answer is $5=129$.

Step-by-step explanation:

Consider the given pattern as follows:

$1=5$

$2=12$

$3=31$

$4=68$

Step 1 of 5

Rewrite the pattern $1=5$ as follows:

⇒ $1=1+4$

⇒ $1=1^3+4$

Step 2 of 5

For the pattern $2=12$, we have

⇒ $2=8+4$

⇒ $2=2^3+4$

Step 3 of 5

Similarly, we can write the pattern $3=31$.

⇒ $3=27+4$

⇒ $3=3^3+4$

Step 4 of 5

Rewrite the pattern $4=68$ as follows:

⇒ $4=64+4$

⇒ $4=4^3+4$

Step 5 of 5

After observing the pattern, we can conclude that the pattern has the sequence of the type as follows:

⇒ $n=n^3+4$ . . . . . (1)

Substitute the value $5$ for $n$ in the (1) as follows:

⇒ $5=5^3+4$

⇒ $5=125+4$

⇒ $5=129$

Final answer: The next term is $5=129$.
