IgorC [24]

\frac{5}{7}  \:  -  \:  \frac{3}{2}

  • First, we find the <u>lowest common denominator</u> which is "14", we put it in the common numerator.

\frac{10 \:  -  \: 21}{14}

  • We subtract the numbers.

\boxed{ \bold{- \frac{11}{14} }}

For this case we first define the variable:
 x = number of terms.
 The equation that models the problem is:
 f (x) = 3.4 - 0.6x
 We have then that the first four terms are:
 x = 1
 f (1) = 3.4 - 0.6 (1) = 3.4 - 0.6 = 2.8
 x = 2
 f (2) = 3.4 - 0.6 (2) = 3.4 - 1.2 = 2.2
 x = 3
 f (3) = 3.4 - 0.6 (3) = 3.4 - 1.8 = 1.6
 x = 4
 f (4) = 3.4 - 0.6 (4) = 3.4 - 2.4 = 1
 Answer:
 
The rule for the sequence is:
 
f (x) = 3.4 - 0.6x
