Question
2807, 1400, 697, 347, 171, 84, 41, 20
Options
A. 697
B. 347
C. 371
D. 84

Correct Answer

347

Explanation

From the given figure , we can see that
First term = 2807
Second term = ( First term - 7 ) � 2 = 1400
Third term = ( Second term - 6 ) � 2 = 697
? Second term = ( 2807 - 7 ) � 2 = 1400 ;
? Third term = ( 1400 - 6 ) � 2 = 697 ;
? Fourth term = ( 697 - 5 ) � 2 = 347; 347 is wrong. It should be 346.
? Fifth term = ( 346 - 4 ) � 2 = 171 ;
? Sixth term = ( 171 - 3 ) � 2 = 84 ;
? Seventh term = ( 84 - 2 ) � 2 = 41 ;
? Eighth term = ( 41 - 1 ) � 2 = 20
Hence, 347 is wrong. It should be 346.
