Answer:
The nth terms: 15,24,33,42,51,60,69,78,87,96,105...
Step-by-step explanation:
The nth term of an arithmetic sequence is given by an = a + (n – 1)d. So, to find the nth term, substitute the given values a = 2 and d = 3 into the formula
She should get 84 in her fifth test to have an average of 80
(75 + 81 + 77 + 83 + x)/5 = 80
(316 + x)/5 = 80
[(316 + x)/5] (5) = 80(5)
316 - 316 + x = 400
316 + x = 400 - 316
x = 84
8 - 5(12x + 8)
8 - 60x - 40
-60x + (8 - 40)
-60x - 32
hope that helps, God bless!
