Graph the six terms of a finite series where a1 = −3 and r = 1.5.
s344n2d4d5 [400]
We are given the first term and the common ratio, this means they belong to a geometric series.

For the given series:

a_{1}=-3 \\ 
r=1.5

Each term of the geometric series is obtained by multiplying the previous term by common ratio.

So the next terms will be:

-4.5, -6.75, -10.125, -15.1875, -22.78125

The general formula for the G.P would be:

a_{n}=-3(1.5)^{n-1}

On plotting the series, the result will be like this:

Juan scored 15 points more on this test than
maw [93]

Juan's least integer scores in both tests will be 85 and 100 respectively.

  • Test average of his two scores is atleast 92

Let :

  • Score on test 1 = b
  • Score on test 2 = b + 15

Average score can be related thus:

  • (Sum of score ÷ number of test) ≥ 92
  • (b + b + 15) ÷ 2 ≥ 92
  • (2b + 15) ÷ 2 = 92
  • 2b + 15 = 184
  • 2b = 184 - 15
  • 2b = 169
  • b = 169 ÷ 2
  • b = 84.5

Therefore, since both scores are integers, his least scores on both tests will be ::

  • 85 and (85 + 15) = 100
