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

Olin [163]

Answer: 433

Step-by-step explanation:

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

We can see that the terms ha common difference as :-

$42-19=23\\65-42=23\\88-65=23$

Thus, its an Arithmetic progression with common difference (d)=23

The formula to find the nth term is :-

$a_n=a_1+(n-1)d$

Now, the 19th term of the given sequence :-

$a_{19}=19+(19-1)(23)\\\\=19+(18)(23)\\\\=19+414=433$

Hence, the 19th term of 19,42,65,88,... is 433.
