Question

Lola already has 6 pennies, and she plans to save more. In her first week

Answer 1

Answer: $P=6(2)^{w-1}$

Step-by-step explanation:

Here, the money saved each week follows geometric progression with a common ratio r= 2 and first term a= 6.

In geometric progression, nth term  = $ar^{n-1}$

Substitute  r= 2 , a= 6 and n=w, we get

wth term = $6(2)^{w-1}$

The equation can be used to determine the number of pennies, P, Lola will save during week w of saving pennies:

$P=6(2)^{w-1}$
