Question

how many multiples of 4 lie b/w 10 and 205​

Answer 1

Answer:

N=50

Step-by-step explanation:

204= 8+(n-1)4

204= 8+4n-4

204=4+4n

204-4=4n

200=4n

200/4=n

50=n

Answer 2

Answer:

First and Last Multiple of 4 b/w 10 & 205 is 12 and, 204.

• a = 12
• l = 204
• d = 4

• Nth Term of the AP :

⇒ l = a + (n – 1)d

⇒ 204 = 12 + (n – 1)4

⇒ 204 – 12 = (n – 1)4

⇒ 192 = (n – 1)4

⇒ 192 /4 = (n – 1)

⇒ 48 = (n – 1)

⇒ 48 + 1 = n

⇒ n = 49

∴ Number of Multiples will be 49.
