For each sequence, write an explicit formula. a) 1, -10, 100, -1000, 10,000

b) 10.2, 2.2, -5.8, -13.8, -21.8

b) 10.2,2.2,-5.8-13.8,-21.8 (I actually don't know)

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

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
