-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.

step-by-step explanation: g=6

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
