Ann and Tom want to establish a fund for their​ grandson's college education. What lump sum must they deposit at an 8.2​% annual
GaryK [48]
Compound interest formula = a=P(1+r/n)^nt

P= lump sum to deposit (solving for)

A= amount accumulated over the entire time (20000)

n= number of times interest is compounded annually (1)

r= rate of interest (0.82)

T= total number of years (15)

20000=P(1+0.082/1)^1*15

20000=P(1.082)^15
20000=P(3.26143638)
20000/3.26143638=P
P=$6132.2674

Find 10th term of a geometric sequence whose first two terms are 2 and -8. Please answer!!
Shalnov [3]

Answer:

The 10th term is -524,288

Step-by-step explanation:

The general format of a geometric sequence is:

a_{n} = r*a_{n-1}

In which r is the common ratio and a_{n+1} is the previous term.

We can also use the following equation:

a_{n} = a_{1}*r^{n-1}

In which a_{1} is the first term.

The common ratio of a geometric sequence is the division of the term a_{n+1} by the term a_{n}

In this question:

a_{1} = 2, a_{2} = -8, r = \frac{-8}{2} = -4

10th term:

a_{10} = 2*(-4)^{10-1} = -524288

The 10th term is -524,288
