​

Answer 1

hey mate....!!

here is ur ans...

An=a+(n-1)d

241=7+(n-1)6

241-7=(n-1)6

234=(n-1)6

234/6=n-1

39=n-1

n=40

now middle term = n/2=20

An=7+(20-1)6

=7+19×6

=7+114

=121

hope it helps...❤❤

Answer 2

Answer:

An=a+(n-1)d

187=7+(n-1)6

180=(n-1)6

n-1=30

n=31

n is odd then (n+1/2)

16th term is middle term of this ap

A16=a+15d

= 7+15×6

= 97
