789, 645, 545, 481, 440, 429, 425
(a)645
(b)545
(c)481
(d)440
(e)429
Answer
Explanation
2nd term = 1st term – $(12)^2$ = 789 – 144 = 645; 3rd term = (2nd term) – $(10)^2$ = 645 – 100 = 545; 4th term = (3rd term) – $(8)^2$ = 545 – 64 = 481; 5th term = (4th term) – $(6)^2$ = 481 – 36 = 445. 440 is wrong.
