Answer:
Human population, now over 7 billion, cannot continue to grow indefinitely. There are limits to the life-sustaining resources earth can provide us. In other words, there is a carrying capacity for human life on our planet. Carrying capacity is the maximum number of a species an environment can support indefinitely.
It is projected that the world's population will continue to grow and will reach nearly 10 billion by 2050. While in other regions growth will slow significantly, in Sub-Saharan Africa, the population is projected to double by 2050, an expansion of nearly 10 times relative to 1960, from 227 million to 2.2 billion.
This is a geometric sequence with first term 2 and common ratio 5.
an = a1 r^(n-1) IS THE GENERAL FORM SO HERE IT IS:-
an = 2(5)^(n-1)
