Answer 2

Answer:

The answer to the given question is 2,2,5,12,62,749,46450,34791112

Step-by-step explanation:

Given :

2,2,5,12,62,749,46450, ---

To find :

we have to find the number that comes next in the given series.

Solution :

To find the next number, we must find the logic between every number in the series.

The logic between the numbers is obtained as

4 th number = Product of previous two numbers + the first number

$(2 \times 5) + 2 = 12$

(second x third number ) + first number = fourth number.

The fifth number is obtained by (third number x fourth number )+second number.

$(12\times 5) + 2 = 62$

The sixth number is obtained by

(fifth number x fourth number )+ third number

$(62 \times 12) + 5 = 744 + 5 = 749$

The seventh number is obtained by

(sixth number x fifth number )+ fourth number

$(749 \times 62) + 12 = 46438 + 12 = 46450$

Finally, the last unknown number is obtained by

the eighth number = (seventh x sixth number )+ fifth number

$(46450 \times 749) + 62 = 34791050 + 62 \\ = 34791112$

Therefore, the final answer to the given question is

2,2,5,12,62,749,46450,34791112
