​

Answer 1

Answer:

The natural numbers from 10 to 250 th n n −162 −3 divisible by 4 are 12, 16, 20, …,248 The above sequence is an A.P. ∴ a = 12, d = 16 – 12 = 4 Let the number of terms in the A.P. be n. Then, tn = 248 Since, tn = a + (n – 1)d ∴ 248 = 12 + (n – 1)4 ∴ 248 – 12 = (n – 1)4 ∴ 236 = (n – 1)4 ∴ n – 1 = 236/4 ∴ n – 1 = 59 ∴ n = 59 + 1 = 60 ∴ There are 60 natural numbers from 10 to 250 which are divisible by 4.Read more on Sarthaks.com - https://www.sarthaks.com/845109/in-the-natural-numbers-from-10-to-250-how-many-are-divisible-by-4?show=845111#a845111
