1364

Step-by-step explanation:

∑ 4ⁿ   from n = 1 to 5

n = 1:    4¹   =    4

n = 2:   4²   =   16

n = 3:   4³   =   64

n = 4:   4⁴   =  256

n = 5:   4⁵   = 1024

                     1364

You can also use the formula: S = [a(1 - rⁿ)]/(1 - r)

S =

  =

  =

  =

  = 1364

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
