What is the missing constant term in the perfect square that starts with x
+ 182 ?

C) 871 883 885 889 893 894 902 904 909 909

Step-by-step explanation:

A Stem and Leaf Plot is a table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).

i.e. the given data will be split by making I digit as stem and last digits as leaf.  Some times stem and again another branch of stem and then leaves would be done

Seeing our data we find that 87 is stem and 1 is leaf and hence the data is 871.

Similarly other entries are  883 885 889 893 894 902 904 909 909

Hence option C is right.
