Answer:

Step-by-step explanation:

arithmetic sequences can be written as

a_n = a_1 + (n-1)d\\

in this case

a_n = a_1 + (n-1)(-3)\\and\\17 = a_1 +(4-1)(-3)\\17= a_1 + (3)(-3)\\17= a_1 - 9\\a_1 = 26\\so\\a_n = 26 - 3(n-1)\\a_n = 26 -3n + 3\\a_n = 29 - 3n

Debora [2.8K]

Answer:

37 cents

Step-by-step explanation:

Given that a grocery store sells Swiss cheese

Rate per pound = 5.90 dollars

1 pound =16 oz,

Hence cost of 16 ounces is given as 5.90

SO cost of one ounce of Swiss cheese =\frac{5/90}{16} =0.36875

Or 36.875 cents

Round off to nearest cent as

37 cents since after decimal digit 8 is more than 5.

Hence answer is 37 cents
