Which expression represents the series 1+5+25+125+625

The given series is written in expression form as

Step-by-step explanation:

Given : series 1+5+25+125+625

We have to find the expression  for the given series 1+5+25+125+625

Consider the given series 1+5+25+125+625

1 can be written as

5 can be written as

25 can be written as

125 can be written as

625 can be written as

Thus, the general representation of the series is for n is 0 to 4.

Thus,  The given series is written in expression form as

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
