In an arithmetic sequence, a17 = -40 and
a28 = -73. Explain how to use this information to write a recursive formula for this sequence.
WILL MARK BRAINLIEST

DISCLAIMER: I MIGHT BE WRONG I LEARNED THIS LAST YEAR SO I AM A BIT RUSTY PLEASE DONT HATE AND REPORT ME :)

a(n)=a(n-1)-3

Step-by-step explanation:

The recursive formula is a(n)=a(n-1)+d

d= common difference

n= the number of whichever term you are finding

Now we will find the common difference

28-17=11

the difference between -40 and -73 is -33.

commondifference is -3

a(n-1)-3

sorry if this is unorganized

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
