Analyzing +4 | -1

{a_1},{a_2}, \ldots .{a_{50}}

are in GP, then

\frac{{{a_1} - {a_3} + {a_5} - ... + {a_{49}}}}{{{a_2} - {a_4} + {a_6} - ... + {a_{50}}}}

is equal to

View answer and explanation

Correct option: C

\frac{{{a_1}}}{{{a_2}}}

Option C (

\frac{{{a_1}}}{{{a_2}}}

) is correct because by expressing each term of the numerator and denominator in terms of

a_1

and the common ratio r, the expression simplifies to

\frac{a_1}{a_2}
