Here are the first five terms of a number sequence. 3 7 11 15 19 Write down an expression, in terms of n, for the nth term of the number sequence.

4n - 1

Step-by-step explanation:

The expression is

As we know that

a + (n - 1)d

where

a denotes the first term

n denotes the nth term

And, d denotes the difference

Now

3 + (n - 1) 4

3 + 4n - 4

4n - 1

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
