Answer:

answer is c. 9

Step-by-step explanation:

General equation=nth term=((n-1)th term +1)*(n-1)

First term=3

Second term=(first term+1)*1

4=(3+1)*1

Similarly 3rd term should be

Third term=(second term+1)*2

10=(4+1)*2

but it is was replaced in the sequence with 9

Consider original number for next terms

Fourth term=(10+1)*3=33

Fifth term=(33+1)*4=136

Sixth term=(136+1)*5=685

Seventh term=(685+1)*6=4116

the odd number is 9.
