Write the Recursive Rule for the sequence:
skad [1K]

A formula is recursive if it expresses the term a_n in terms of the previous one(s) a_{n-1},\ a_{n-2},\ \ldots,\ a_1

In this case, every term is 7 more than the previous one, so the formula for a_n will only involve a_{n-1}:

a_n = a_{n-1} + 7

In fact, this formula is simply saying: for every index n, the term with that index is 7 more than the term before.

Also, we have to specify the starting point (otherwise we would go backwards indefinitely), so the complete recursive formula is

a_n = a_{n-1} + 7,\quad a_1 = 2

which means: start with 2 and generate every other term by adding 7 to the previous one.

Is k=4 a solution of 4 K + 7=7 k-1
MAVERICK [17]

Answer:

k=8/3

Step-by-step explanation:

Let's solve your equation step-by-step.

4k+7=7k−1

Step 1: Subtract 7k from both sides.

4k+7−7k=7k−1−7k

−3k+7=−1

Step 2: Subtract 7 from both sides.

−3k+7−7=−1−7

−3k=−8

Step 3: Divide both sides by -3.

−3k

−3

=

−8

−3

k=
