Answer 2

Answer:

36

Step-by-step explanation:

36 natural numbers lie between 18 squared and 19 squared.

Step-by-step explanation:

To find : How many natural numbers lie between 18 square and 19 square?

Solution :

The square of numbers is

18² = 324

19² =361

The natural numbers between  and  are the numbers in the sequence

325, 326,…….., 359, 360  this form an A.P

Where, first term is a=325

Common difference is d=1

Last term is l=360

Using last term formula,

l = a+(n-1)d

360= 325+(n-1)×1

360-325=n-1

35=n-1

35+1=n

36=n

Therefore, 36 natural numbers lie between 18 squared and 19 squared
