Question

find the series 4,20,6,42,8,72,10,........​

Answer 1

Answer:

110

Step-by-step explanation:

The pattern is simple...

The 1-digit even number is multiplied with its consecutive number to give the next 2-digit number, then continued by the next even number.

Ex:  4 x 5 = 20

      6 x 7 = 42

      8 x 9 = 72

So, 10 x 11 = 110

Therefore, your answer is 110.

But if you ask series...the continuation will be-

110,12,156,14,210,16,272 and so goes on.....

Hope this helps...

Answer 2

Answer:

114 is the next number in the series.

Step-by-step explanation:

Explanation:

Given in the series, 4,20, 6, 42, 8, 72, 10....

Let the next number be x.

• Here we can see that, third number is 2 more than first number,  fifth number if 2 more than third one and 7th number is 2 more than fifth one.

• And now we can see that, 4th number is 22 more than 2nd number and 6th number is 32 more than fourth number.

Similarly, 8th place number  will be 42 more than the 6th number.

So, x = 72 + 42 = 114.

Final answer:

Hence, 114 is the next number in the given series.
