Answer 2

Given:

The multiples of 9.

To find:

How many multiples of 9 lie between 10 and 300?​

Solution:

As we have to find the multiples of 9 lie between 10 and 300,

so, a number after 10 that is a multiple of 9 is 18, similarly, a number before 300 that is a multiple of 9 is 297.

So, we get a series,

18, 27,......,297

here, a = 18, d = 27 - 18 = 9

we use the formula,

Tn = a + (n - 1) d

297 = 18 + (n - 1)9

297 = 18 + 9n - 9

288 = 9n

n = 32

Therefore, there are 32 multiples of 9 that lie between 10 and 300
