First term:  a(1) = 4; common ratio:  r = 2

Then:

a(n) = 4(2)^(n-1)

Check:  Predict the 4th term using this formula:

a(4) = 4(2)^3 = 4(8) = 32  (correct)

34kurt

Step-by-step explanation:

The line is

j --------K----------M---------N---------L

6. 4. 4. 4

JN = 14

KM = 4

KM = MN = LN =4

JK = 14 - (KM+MN)

JK = 14 - 8 = 6

JK = 6

MN = 4

LJ = 18

KN = 8

MJ = 10

NL = 4

Find the 6th term of a geometric sequence with t1=5 and r = -1/2
andreyandreev [35.5K]
Same as before, to make the formula do

t(1) * (r)^n-1
So 5 * (-1/2)^n-1
Therefore 
5*(-1/2)^5
