there are 76 numbers between 256 and 789 are exactly divisible by 7
and we can find this from the formula of Arithmetic Progression,
L=a+(n-1)d
(where a is first term “259”
)d is “7”
L is 784(which is big number before 789 can be exactly devided by 7)
n=? therfore,
L=a+(n-1)d
put the values
784=259+(n-1)7
784–259=(n-1)7
525/7=n-1
75+1=n
n=75+1 = 76
