The number that are divisible by 7 between 30 and 500 are as follows :
35, 42,49,.....,497
It will form an AP with first term, a = 35 and common difference, d = 7
Let there are n terms in the AP.
nth term of an AP is given by :
Putting all the values,
Now, the sum of n terms of an AP is given by :
Putting all the values,
Hence, the sum of the numbers that are divisible by 7 between 30 and 500 is 17822.
Answer:
