Answer:

Step-by-step explanation:
<u>Recursive sequence
</u>
In a recursive sequence formula, each term
is computed as a function of one or more previous terms. In the formula

n is the number of the term we want to calculate. If n=8, then the formula becomes

We can see
is the previous term. It means we need
to be able to compute
. But we also need
to compute
and so on until some known data is reached. The question provides five terms,




Answer:
y = 0.5x - 5.5
Step-by-step explanation:
slope = 0.5, so this is the x coefficient.
y intercept = -2 - (7 x 0.5) = -5.5
Answer:
second graph
Step-by-step explanation:
Answer:
670
Step-by-step explanation:
(3*1+2)+(3*2+2)+........(3*20+2)=670
75% of x = 63
<span>75/100 * x = 63 </span>
<span>So dividing by 75 / 100 on both sides </span>
<span>x = 63 / 75 / 100 </span>
<span>x = 63*100/75 </span>
<span>x = 84 </span>
<span>The number is 84 </span>
<span>So 75% of 84 = 63! </span>
<span>Hope that helps!</span>
