Sean took 6 tests and currently has an average of a 90. His range of his scores was 18 and the mode of the test scores is 89.

what is the question?

Step-by-step explanation:

Below.

Step-by-step explanation:

Total scores = 6*90 = 540.

He had more than one 89 ( mode) and max score - min score = 18.

Let max score = x then min = x-18.

Lets say he has 3 89's then

x +  x - 18 + 3*89 + y  = 540  where y is another score then:

2x + 249 + y = 540

2x + y =  291

x = 98 and y = 95 will fit this so the 6 scores could be

80, 89, 89, 89, 95, 98.

answer: the answer is 23

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
