It is interesting series .
37 , 511, 713
37 is the combination of two prime numbers 3 and 7
511 is the combination of two prime numbers 5 and 11
713 is the combination of two prime numbers 7 and 13
so, the next term should be combined of two prime numbers
option (c) is the only one which are combination of two prime numbers 11 and 17
Hence, answer is (c)
Method 2 :-
37, 511, 713 ,.....
Can you write it 3, 7, 5, 11, 7, 13 ,...
now, see 1st , 3rd , 5th places of series
3 , 5 , 7, so the next place 7th should be 11 [ 9 can't be possible because 9 is not prime number. Next so, after 7 ,11 is prime number ]
Similarly see 2nd , 4th , 6th places
7, 11, 13 so, the next place 8th should be 17 [ because 15 can't be possible because it is not a prime no]
Now, 7th place and 8th place = 11, 17 = 1117
Hence, option (c) is correct.
