Ap is 5,15,25.....n
a=5 and d=15-5=10
31st term=a+30d
⇒5+30*10
⇒5+300
31st term =305
an=305+130=435
a+(n-1)d=435
5+(n-1)10=435
(n-1)10=435-5
(n-1)=430/10
n-1=43
n=44
∴ the 44th term of the given AP will be 130 more than its 31st term
a=5 and d=15-5=10
31st term=a+30d
⇒5+30*10
⇒5+300
31st term =305
an=305+130=435
a+(n-1)d=435
5+(n-1)10=435
(n-1)10=435-5
(n-1)=430/10
n-1=43
n=44
∴ the 44th term of the given AP will be 130 more than its 31st term

It's 31st term and will be
= a + (n-1)d
= 5 + (31-1)10
= 5+300
=305
As per question, required no. is

=435
= a + (n-1)d
= 5 + (31-1)10
