nth term = a₁rⁿ⁻¹ = ½(-8)ⁿ⁻¹

This can be further simplified to (-1)ⁿ⁻¹2³ⁿ⁻⁴

The table below shows 10 data values 125 138 132 140 136 136 126 122 135 121 What values of minimum, Q1, median, Q3, and maximum

Troyanec [42]

We have to put the numbers in order..
(121,122,125, 126,132),M,(135,136,136,138,140)

minimum : (smallest number) = 121
Q1 : 125
Q2 (median) : (132 + 135) / 2 = 267/2 = 133.5
Q3 : 136
maximum : (largest number) = 140
