Question

How many multiples of 6 lie between 10 and 250​

Answer 1

Hey mate here is your answer....

Ans : 12, 18, 24 ................. ,246.

a = 12 , d = 18 - 12 = 6 , an = 246

an = a + (n - 1) d

246 = 12 + (n - 1) 6

246 - 12 = (n - 1) 6

234 = (n - 1) 6

234 / 6 = (n - 1)

39 = n - 1

39 + 1 = n

40 = n.

Therefore, 40 multiples of 6 lie between 10 and 250.

Hope it help you. So, plzzz mark my ans as brainliest answer.....

Answer 2

Answer:

there are 40 number of multiple of 6 lie between 10 and 250

Step-by-step explanation:

we know that an= a + ( n-1) d

6,12,18,......,246

here an is last last term before 250 which is multiple of 6

a is 1st term after 10 which is multiple of 6

and d is difference between 1st two term

here a= 12 and d= 12-6= 6 and an= 246

246= 12+ (n-1) 6

12+6n-6=246

6+6n=246

6n=240-6

6n=240

n=240/6

n= 40
