    As the numbers are divisible by both 2 and 5,so their last digit will always be 0. hence the series are 110,120,130,....,990

    here a=110,d=10,an=990

    an=a+(n-1)d

    990=110+(n-1)10

    (n-1)10=880

    n-1=88

    n=88+1

    n=89.

    thus the number of natural numbers between 102 and 998 which are divisible by both 2 and 5 is 89.
