given the formula for an arithmetic sequence f(7) = f(6) + 4 written using a recursive formula, write the sequence using an arithmetic formula.

f(7) = f(1) + 24
f(7) = f(1) + 20
f(7) = f(1) + 12
f(7) = f(1) + 4

f(7) = f(1) + 24

Step-by-step explanation:

from f(7) = f(6) + 4

we can observe that any term is basically the previous term in the progression plus 4 which means:

f(6) = f(5) + 4

f(5) = f(4) + 4

f(4) = f(3) + 4

f(3) = f(2) + 4

f(2) = f(1) + 4

If we start substituting the lower terms into next highest term, starting from the bottom and working our way up, we will get:

f(3) = f(2) + 4 = [ f(1) + 4 ] + 4 = f(1) + 8

f(4) = f(3) + 4 = f(1) + 8 + 4 = f(1) + 12

f(5) = f(4) + 4 = f(1) + 12 + 4 = f(1) +16

f(6) = f(5) + 4 = f(1) + 16 + 4 = f(1) + 20

f(7) = f(6) + 4 = f(1) + 20 + 4 = f(1) + 24

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
