The sum of the first n terms of a sequence is given by 44(1/2)^n.calculate the first 3 terms

Maths and science 
Reiny,
term(1) = 4  4(1/2)^1 = 4  2 = 2
term(2) = 4  4(1/2)^2= 44(1/4) = 3
term(3) = 44(1/2)^3
= 4  4(1/8)
= 4  4/8
= 4  1/2 = 3 1/2 or 7/2 or 3.5
so to get any term, e.g. term(5), replace n with the term number you want, in this case n=5
