Question

which term of AP 5 15 25 will be 130 more than its 31st term​

Answer 1

Answer:

Ap is 5,15,25.......

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

It means the 44th term of the given AP will be 130 more than its 31st term.
