Answer: 10.4

Step-by-step explanation:

Let the number that Colin is thinking of be represented as x.

We are informed that Colin halves the number and gets an answer of 5.2. This can be written as:

x ÷ 1/2 = 5.2

0.5x = 5.2

Divide through by 0.5

0.5x/0.5 = 5.2/0.5

x = 10.4

The number is 10.4

A sequence can be generated by using an = an-1 + 4, where a1 = 6 and n is a whole number greater than 1. What are the first four

Firlakuza [10]

Answer:

The first four terms are 4,8,12,16

Step-by-Step Explanation:

The given relation between the nth term and it's previous term is given by:

$\boxed{an = an - 1 + 4}$

GiveN:

a1 = 4

Now finding the other three terms of the AP with the given relation.

$a2 = a1 + 4$

Putting a1 = 4,

$a2 = 4 + 4 = 8$

Now, Third term:

$a3 = a2 + 4$

Putting a2 = 8,

$a3 = 8 + 4 = 12$

Now, Fourth term:

$a4 = a3 + 4$

Putting a3 = 12,

$a4 = 12 + 4 = 16$

Hence, The first four terms of the AP is 4, 8, 12 & 16.
