The expression that gives the goal for the 52nd week is 20(2)⁵¹.
Week 1 2 3 4 5
Goals 20 40 80 160 320
This means the numbers are goals are increasing geometrically.
What is a geometric progression?
A geometric progression is a series in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio.
We know the nth term of a GP = arⁿ⁻¹
Where a is the first term and r is the common ratio.
In our problem, a=20 and r=40/20=2
So, the 52nd term of the GP = 20(2)⁵²⁻¹
The 52nd term of the GP =20(2)⁵¹
Hence, the expression that gives the goal for the 52nd week is 20(2)⁵¹.
