Week$\color{red}{1}$, account $A_\color{red}{1}= 150 +(\color{red}{1}-1)*25$
Week$\color{red}{2}$, account $A_\color{red}{2}= 150 +(\color{red}{2}-1)*25$
Week$\color{red}{3}$, account $A_\color{red}{3}= 150 +(\color{red}{3}-1)*25$
Week$\color{red}{4}$, account $A_\color{red}{4}= 150 +(\color{red}{4}-1)*25$
Can you write the formula for Week$\color{red}{n}$ ??
