Find the recursive definition for this sequence
2,6,18,54,162

Step-by-step explanation:

Given

Sequence: 2, 6, 18, 54, 162,

Required

Determine the 15th term

The above sequence is a geometric sequence. So, first, we calculate the common ratio (r)

The 15th term is calculated as thus:

Where

and

The 15th term is 9,565,938

Step-by-step explanation:

Given

Sequence: 2, 6, 18, 54, 162,

Determine the 15th term

The above sequence is a geometric sequence. So, first, we calculate the common ratio (r)

The 15th term is calculated as thus:

Where

and

The 15th term is 9,565,938

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

The answer is in the image 

The solution is given in the image below

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

The answer is in the image
