We know that after each number they add 3 and after a letter they go 3 steps for another letter
so we will have
4D7G10J13M
I hope that's help:0
The next value in the given series is:
M
By looking at the series we see that the first a number comes up and then a character is a alphabet corresponding to the number to which they come in the English alphabet.
For example--
A comes in the first position.
B in second.
C in third and so on.
Here we may see that:
4--D
(D comes up in the fourth position of English alphabet)
7--G
(Similarly G comes up in the 7th position)
10---J
Now we have to find the alphabet which comes in the 13th position.
We know that M comes up in the 13th position.
Hence, we get:
13---M
Hence, the series could be seen as:
4D7G10J13M
(Also the number in increasing by 3 each time )
