Question:
If a, b, c are in A.P., a, mb, c are in G.P., then a, m2b, c are in
If a, b, c are in A.P., a, mb, c are in G.P., then a, m2b, c are in
Options:
- A.P.
- G.P.
- H.M.
- H.P.
- A.P.
- G.P.
- H.M.
- H.P.
Correct Answer: a)
Explanation:
‘ If the numbers a, b, ¢ are in A.P. we ha√e b= x2° .__(i) ‘
1 Since a, mb, c¢ are in G.P. we get (mb)? =ac ….(ii)
5)?
Now nb = ELOR = Ze
1 = a, m”b, c are in H.P.
