Answer:
dont now the answer for the 1 one
Step-by-step explanation:
2. In the slope formula, (y2-y1)/(x2-x1), The 2 is the y2 and the 1 is the y1. And, naturally, the 5 is the x2 and the 1 is the x1. if u do it in this way u will get the answer this is an example
4.It is possible to determine a formula for linear sequences, i.e. sequences where the difference between successive terms is always the same.
The first differences for the number pattern
11 14 17 20 23 26 ...
are 3 3 3 3 3
If we look at the sequence 3n, i.e. the multiples of 3, and compare it with our original sequence
our sequence 11 14 17 20 23 26
sequence 3n 3 6 9 12 15 18
we can see easily that the formula that generates our number pattern is
nth term of sequence = 3n + 8
i.e. un = 3n + 8
If, however, we had started with the sequence
38 41 44 47 50 53 ...
the first differences would still have been 3 and the comparison of this sequence with the sequence 3n
our sequence 38 41 44 47 50 53
sequence 3n 3 6 9 12 15 18
would have led to the formula un = 3n + 35.
In the same way, the sequence
–7 –4 –1 2 5 8 ...
also has first differences 3 and the comparison
our sequence – 7 – 4 – 1 2 5 8
sequence 3n 3 6 9 12 15 18
5. odd +odd =even
odd +even =odd
even +even =even
even +odd =odd
I think that is right
