-4n + 5 is the algebraic form of an arithmetic sequence. What is its first term and common difference?

a1=1

- 4 (common difference)

Step-by-step explanation:

a1=-4*1+5=-4+5

a1=1

a2=-4*2+5=-8+5=-3

common difference=a2-a1=-3-1=-4

1 and -4.

Step-by-step explanation:

First term is when n = 1 so it is:

-4(1) + 5 = 1.

The common difference is the coefficient of n which is -4.

For example the 2nd term = -4(2) + 5 = -3.

Common difference =  2nd term - first term

= -3 -1

= -4.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be
