Answer:
<em></em><em></em>
<em></em>
Step-by-step explanation:
<em>To solve this question, we need the area and population of the earth</em>
<em></em><em></em>
<em></em><em> ---- 2018 population</em>
<em></em>
<em>Next is to divide the area by population;</em>
<em></em><em></em>
<em></em><em></em>
<em></em>
<em>Convert to digits</em>
<em></em><em></em>
<em></em>
<em>Divide numerator and denominator by 1000000</em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
<em></em><em> -- Approximated</em>
<em></em>
<em>This means that;</em>
<em>I'll get about 0.067km² area of the earth</em>
Answer:
Step-by-step explanation:
an = a1 * r^(n - 1)
a1 = first term = 5
r = -2
n = nth term of the sequence
so it starts with 5
second term is :
an = a1 * r^(n - 1)......for second term
a2 = 5 * -2^(2 - 1) =
a2 = 5 * -2^1
a2 = 5 * -2
a2 = -10
an = a1 * r^(n - 1)....looking for a3
a3 = 5 * -2^(3 - 1)
a3 = 5 * -2^2
a3 = 5 * 4
a3 = 20
an = a1 * r^(n - 1)....looking for a4
a4 = 5 * -2^(4 - 1)
a4 = 5 * -2^3
a4 = 5 * -8
a4 = - 40
an = a1 * r^(n - 1)...looking for a5
a5 = 5 * -2^(5 - 1)
a5 = 5 * -2^4
a5 = 5 * 16
a5 = 80
an = a1 * r^(n-1)...looking for a6
a6 = 5 * -2^(6 - 1)
a6 = 5 * -2^5
a6 = 5 * -32
a6 = -160
