Answer:
19 m
Step-by-step explanation:
This is Geometric progression with
![\left \{ {{u_1=1,\: u_2 =2} \atop {u_n=2^{n-1}u_1} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bu_1%3D1%2C%5C%3A%20u_2%20%3D2%7D%20%5Catop%20%7Bu_n%3D2%5E%7Bn-1%7Du_1%7D%20%5Cright.)
Then the fomular of sum is
![S=u_1\frac{2^n-1}{2-1} =1\times(2^n-1)=2^n-1\\To\: save\: 1 \:million\: then \; our \:sum \: will \: be\: 1000000\\Hence,\\2^n-1=1000000\\2^n=1000001\\n=log_{2}{1000001}\approx19,9\\Thus, it\:would \;be \:19 \:months \:before\: we\: saved \:1000000 \:pounds](https://tex.z-dn.net/?f=S%3Du_1%5Cfrac%7B2%5En-1%7D%7B2-1%7D%20%3D1%5Ctimes%282%5En-1%29%3D2%5En-1%5C%5CTo%5C%3A%20save%5C%3A%201%20%5C%3Amillion%5C%3A%20then%20%5C%3B%20our%20%5C%3Asum%20%5C%3A%20will%20%5C%3A%20be%5C%3A%201000000%5C%5CHence%2C%5C%5C2%5En-1%3D1000000%5C%5C2%5En%3D1000001%5C%5Cn%3Dlog_%7B2%7D%7B1000001%7D%5Capprox19%2C9%5C%5CThus%2C%20it%5C%3Awould%20%5C%3Bbe%20%5C%3A19%20%5C%3Amonths%20%5C%3Abefore%5C%3A%20we%5C%3A%20saved%20%5C%3A1000000%20%5C%3Apounds)
