B(1)=-54
b(n)=b(n-1) 4/3
what is the 4th term

  -128

Step-by-step explanation:

Evaluate the recursive relation 3 times:

  b(2)= b(1) 4/3 = (4/3)(-54) = -72

  b(3) = b(2) 4/3 = (4/3)(-72) = -96

  b(4) = b(3) 4/3 = (4/3)(-96) = -128

The fourth term is -128.

-128

Step-by-step explanation:

b(1) = -54

b(2) = b(1) ⋅ = -72

b(3) = b(2) ⋅ = -96

b(4) = b(3) ⋅ = -128

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

i hope this is what you were looking for.
