In an arithmetic sequence, the nth term an is given by the formula an=a1+(n−1)d, where a1is the first term and d is the common difference. similarly, in a geometric sequence, the nth term is given by an=a1•rn−1.
use these formulas to determine the indicated term in the given sequence.
the 19th term of 19,42,65,88

433

Step-by-step explanation:

The given sequence : 19,42,65,88,...

Here we can see that the difference in each of the two consecutive terms is 23.  [88-65=23, 65-42=23, 42-19=23]

i.e. it has a common difference of 23.

Therefore, it is an arithmetic sequence .

In an arithmetic sequence, the nth term an is given by the formula , where is the first term and d is the common difference.

For the given sequence ,  and

Then,  to find the 19th term of  the sequence, we put n= 19 in the above formula:-

Hence, the 19th term of  the sequence = 433

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
