In a GP the sum of three numbers is 14, if 1 is
added to first two numbers and 1 is subtracted
from third number the series becomes AP, then
greatest number is -
(A) 8 (B) 4 (C) 24 (D) 16

• ans (A) 8
  LET TERMS ARE a,ar, ar^2
  acc. to problem, 2(ar+1)= a+1+ar^2-1 (A.P.)
  solving a=2, r=2
  i.e. GP is 2,4,8
