The first four terms of a sequence are shown.

5, 15, 45, 135, 405...

Write an explicit function to model the value of the nth term in the sequence such that f(1) = 5.

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
