find the first three terms of the sequence described by the following recursive formula:
an = 3an – 1 + 2 where a4 = 20
a1 =
a2 =
a3 =

need now. how do you do recursive

The recursive formula is given as:

, n is the number of terms

where,

We have to find  first three terms of the sequence.

For n =4 ;

⇒

⇒

Subtract 2 from both sides we have;

Divide both sides by 3 we have;

or

For n = 3;

⇒

Subtract 2 from both sides we have;

Divide both sides by 3 we have;

For n =2

⇒

Subtract 2 from both sides we have;

Divide both sides by 3 we have;

Therefore, the first three terms of the sequence  are:

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46
