21 terms

Step-by-step explanation:

The sum to n terms of a geometric progression is

=

where a is the first term and r the common ratio

Here a = 0.5 and r = 1 ÷ 0.5 = 2

Equate the sum to 1000000 and solve for n , that is

= 1000000

0.5( - 1) = 1000000 ( divide both sides by 0.5 )

- 1 = 2000000 ( add 1 to both sides )

= 2000001 ( take the ln of both sides )

ln = ln(2000001)

n ln2 = ln(2000001) ( divide both sides by ln 2 )

n = = 20.9315....

Thus the number of terms to exceed 1000000 is n = 21
