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
1 answer:
Answer: 433
Step-by-step explanation:
The given sequence : 19,42,65,88,...
We can see that the terms ha common difference as :-
Thus, its an Arithmetic progression with common difference (d)=23
The formula to find the nth term is :-
Now, the 19th term of the given sequence :-
Hence, the 19th term of 19,42,65,88,... is 433.

14. (2x - 1)(x + 7) = 0
Using the zero factor property, we know that either the first or second terms (or both) must be equal to 0 if their product is 0. We can set each term equal to 0 to find the solutions:
2x - 1 = 0
2x = 1
x = 1/2
x + 7 = 0
x = -7
15.
To solve this equation, you first need to set it equal to 0:
Next, it can be factored:
Finally, we can solve just like we did above:
x + 5 = 0
x = -5
x - 2 = 0
x = 2
16.
First, you can simplify by dividing each side by 4:
Now, set the equation equal to 0:
Next, factor:
Finally, find the solutions:
x + 5 = 0
x = -5
x - 5 = 0
x = 5
