Answer:
52
Step-by-step explanation:
As there are 8 terms the terms after pairing will be 4 ( half of the before ).
Total sum of the terms = 16+25+56+43+12+50,+18+52 = 272
Let the sum of 2 number that is paired will be 'x'
x+x+x+x = 272
4x = 272
x = 272/4 = 68
From the above sum of pair should be 68
If the 1st term is 16 then the other term should be 52 ( 68 - 16 )
