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.
