Question

how many nunber are thera between 200and300 which are divisblebby 13​

Answer 1

Answer:

Last term between 200 and 300 which is divisible by 13 is 299. So the last term, Tn is 299. We know that Tn = a+((n-1)*d) where d is the common difference and n is the number of elements.

Answer 2

Answer:

8 number

Step-by-step explanation:

Here the first term between 200 and 300 divisible by 13 is 208. So the first term, a= 208 and the common difference between two consecutive terms is 13.

Last term between 200 and 300 which is divisible by 13 is 299. So the last term, Tn is 299.

We know that Tn = a+((n-1)*d) where d is the common difference and n is the number of elements.

So. Tn = 299 = 208+((n-1)*13)

299–208 = 91 = (n-1) *13

91/13 = 7 = n-1

Therefore, n= 7+1 = 8.
