A) \[\frac{1}{37}\]
B) \[\frac{1}{41}\]
C) \[\frac{1}{45}\]
D) \[\frac{1}{49}\]
Correct Answer: D
Solution :
Considering corresponding A.P. \[a+6d=10\] and\[a+11d=25\]\[\Rightarrow \]\[d=3,\ a=-8\] \[\Rightarrow \]\[{{T}_{20}}=a+19d=-8+57=49\] Hence \[{{20}^{th}}\] term of the corresponding H.P. is \[\frac{1}{49}\].You need to login to perform this action.
