Suppose four distinct positive numbers \( a_{1}, a_{2}, a_{3}, a_{4} \) are in GP. Let \( b_{1}=a_{1}, b_{2}=b_{1}+a_{2}, b_{3}=b_{2}+a_{3} \)
\( \mathrm{P} \) and \( b_{4}=b_{3}+a_{4} \).
Statement 1 The numbers \( b_{1}, b_{2}, b_{3}, b_{4} \) are neither in
W. AP nor in GP.
Statement 2 The numbers \( b_{1}, b_{2}, b_{3}, b_{4} \) are in HP.
[IIT-JEE 2008, 3M]
(a) Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1
(b) Statement-1 is true, Statement-2 is true; Statement-2 is not a correct explanation for Statement-1
(c) Statement-1 is true, Statement-2 is false
(d) Statement-1 is false, Statement-2 is true
