The function of x is .
<u>SOLUTION:</u>
Given that, we have to write a linear function f with function of (-4) =2 and function of 6=(−3).
Now, let the linear function be
Then, function of -4 =
And, function of 6 =
On equating (1) and (2) to find the value of a,
On grouping the common terms,
On substituting the value of (3) in (1) we get,
So, the function of x =
(d) ,
,
(e) 68, 82, 96
(d) note that the terms have a common ratio ( r )
r = =
=
to obtain any term in the sequence, multiply the previous term by

×
=
×
=
(e) note that the terms have a common difference (d )
d = 26 - 12 = 40 - 26 = 54 - 40 = 14
to obtain any term in the sequence, add 14 to the previous term
54 + 14 = 68
68 + 14 = 82
82 + 14 = 96
