Determine the first four terms of the sequence in which the nth term is...

Anon25 [30]

Answer:

1/5, 1/6, 1/7, 1/8

Step-by-step explanation:

The formula for the sequence is (n+3)!/ (n+4)!

The first terms uses n=1

a1 = (1+3)!/ (1+4)! = 4!/5! = (4*3*2*1)/(5*4*3*2*1) = 1/5

The first terms uses n=2

a2 = (2+3)!/ (2+4)! = 5!/6! = (5*4*3*2*1)/(6*5*4*3*2*1) = 1/6

The first terms uses n=3

a3 = (3+3)!/ (3+4)! = 6!/7! = (6*5*4*3*2*1)/(7*6*5*4*3*2*1) = 1/7

The first terms uses n=4

a4 = (4+3)!/ (4+4)! = 7!/8! = (7*6*5*4*3*2*1)/(8*7*6*5*4*3*2*1) = 1/8

ivann1987 [24]

Answer:

The final answer is "$2387.85 and $2594.85".

Step-by-step explanation:

Given values:

The bank statement balance= $2,253.18

The checkbook balance = $2,324.34

outstanding check amounts= $105.50 and $158.10

transit amount= $605.27

account earnin(credits)= $68.51

service charge= $5.00

Adjusted Checkbook Balance =?

Adjusted Statement Balance=?

Adjusted the Checkbook Balance:

checkbook balance = $2,324.34

$\text{total checkbook balance = checkbook balance+ credits}\\$

$= \$ 2,324.34+ \$ 68.51\\\\= \$ 2392.85$

$\text{ Adjust check book balance= total checkbook balance - servicec charge}$

$= \$2392.85 - \$5.00\\\\= \$ 2387.85$

Adjusted the Statement Balance:

bank statement balance= $2,253.18

$\text{total Statement balance = bank Statement balance+ transit amount}\\$

$= \$ 2,253.18+ \$ 605.27\\\\= $ 2,858.45$

$\text{outstanding check amounts = $105.50+ $158.10}$

$= \$263.60$

$\text{ Adjust statement balance= total statement balance - outstanding check amount }$ $= \$ 2,858.45 - \$263.60\\\\= $ 2,594.85$
