Question

The formula for a geometric sequence is an = 25(2) n − 1. What is the 3rd term of the sequence? help me please somebody

Answer 1

Perhaps question should be [a_{n} = 25(2n-1)
Given
\[a_{n} = 25(2n-1)\]
In order to find 3rd term of the given sequence put n=3
so we find
\[a_{3} = 25(2n-1)=25(2\times3-1)=25(6-1)=25\times5=125\]
therefore third term = 125

Answer 2

Perhaps question should be \[a_{n} = 25(2n-1)\]

Answer 3

i dont get it

Answer 4

so is it 75

Answer 5

The formula for a geometric sequence is an = 25(2) n − 1. What is the 3rd term of the sequence?
Answer

50

150

75

100

Answer 6

this is mii question

Answer 7

let n=3 ... and work the math

Answer 8

and it helps if you notate it correctly

an = 25 2^(n-1)

Answer 9

dnt gt it

Answer 10

then you really need to go review the basics of your material .....
