Find a closed form expression that is a solution to the sequence defined by the following recurrence relation and initial conditions (use the method of characteristic equation): az = 30x2 + 40x-2, for all integers k> 2; ao =1, a1 = 2. 1+2x-3x ak-2=c1(4)k-2+c2(-1)k-2 9k=9(4)k+c2(-1)k 5d=3 d=3/5 final: ak=$4k+(-1)

it's both, now can you answer my most recent question?

step-by-step explanation:

thats the first half

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
