Because this is an infinite sequence, we can use the following formula:
a1/r
a1 is the first number in the sequence, r is the rate of change.
To find r, we do the second value divided by the first. So
1/2 / 1 = 1/2
r = 1/2
Now we plug in to our equation.
1 / 1/2
= 2
So your sum is 2
I hope this Helps!
