Answer:

b(4) = -8

Step-by-step explanation:

We are to find the 4th term.

n = 4

b(n) = 1(-2)ⁿ⁻¹

b(4) = 1(-2)⁴⁻¹

b(4) = 1(-2)³

b(4) = 1(-8)

b(4) = -8

Simplify the expression:<br> (3n)(2)
Arlecino [84]

Answer:

Step-by-step explanation:

3n+2)! / (3n-3)! = (3n+2)*(3n+1)*(3n)*(3n-1)*(3n-2)*(3n-3)! divided by (3n-3)! which becomes:

23! / 18! = (23 * 22 * 21 * 20 * 19 * 18! divided by 18! which becomes:

(23 * 22 * 21 * 20 * 19)

the result is 4037880

i used my ti-84 to take 23! and divide it by 18! and i got 4037880.

this confirms the solution is correct.
