Answer 1

an=184
a+(n-1)d=184
7+(n-1)×3=184
(n-1)=(184-7)/3
n-1=177/3
n=59+1
n=60

now
a7=184+(7-1)×-3
=184+6×-3
=184-18
=166

hope this will be helpful :-)

Answer 2

Hey ,Here's ur answer ,

In the given A.P,

t1 (a)=7
t2=10
t3=13
tn=184,

d (common difference)
=t2-t1
=10-7
=3

Using the formula ,

tn=a+(n-1)d
184=7+(n-1)3----------{substituting the values of tn ,a and d}---------
184=7+3n-3
184=3n+4
184-4=3n
180=3n
n=180÷3
n=60

The seven term of an A.p,

tn=a+(n-1)d
t7
=7+(7-1)3
=7+6×3
=7+18
=25

seventh term of A.p is 25

Hopeit helps you!
