Answer:
Step-by-step explanation:
In a geometric sequence, consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as
an = a1r^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the given sequence,
a1 = - 5
r = 15/- 5 = - 3
Therefore, the explicit rule for this sequence is
an = - 5(- 3)^n - 1
600 * 0.85 (the way to work out 85% of something) = 510 flights on time
40.75
3/4 = 0.75
40 + 0.75= 40.75
3 * 5x
3 * 5(2)
3 * 10
30
