Analyzing +4 | -1

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

and

b_4=b_3+a_4

Statement- 1 The numbers

b_1, b_2, b_3, b_4

are neither in AP nor in GP.

Statement -2 The numbers

b_1, b_2, b_3, b_4

are in

\mathrm{HP}

View answer and explanation

Correct option: C

Statement- 1 is true, Statement-2 is false

Option C (Statement-1 is true, Statement-2 is false) is correct because the numbers

b_1, b_2, b_3, b_4

are neither in AP nor in GP nor in HP.
