If n is an odd number greater than or equal to 3, can n + 1 ever be prime? What if n equals 1?

No, because when adding 1 to any odd number it will become even, and all even numbers besides 2 are not prime. This means that if n was 1 the resulting number would be prime, since 2 is prime.

The repayment schedule is for a $1,300 loan at 7.5% for 6 months. What is the amount for interest at payment 5?
max2010maxim [7]

Answer: The answer is $2.77.


Step-by-step explanation:   Given that we have to pay the loan of $1300 at interest rate of 7.5% in 6 months. According to the table,

Amount for interest in payment 1 = $8.13,

Amount of interest in payment 2 = $6.79

and

Amount of interest in payment 3 = $5.45.

We can see here that the difference in the amounts to be paid in consecutive months will be same, i.e., the payments will form an arithmetic progression (A.P.).

The common difference = 8.13-6.79=6.79-5.45=1.34.

Therefore, amount of interest in payment 4 = $(5.45-1.34) = $4.11

and amount of interest in payment 5 = $(4.11-1.34) = $2.77.

Please see the attached modified table.

Thus, the answer is $2.77.

Darina [25.2K]
I broke it all the way day half of 51 is 25 in a half and half of 25 is 12 in half so if Jimmy lifted twice as much he may have lifted 25 in a half and bob left 12
