Ed buys vase for £24 and adds 25% onto the price before putting it into his shop window. what does the price tag say in the window? I thought £30 but apparently it's wrong

£30

Step-by-step explanation:

From the question, we know that:

Ed buys vase for £24 and adds 25% onto the price before putting it into his shop window.

Step 1

We find the amount added onto the price.

This is calculated as:

£24 × 25%

£24 × 25/100

= £6

Step 2

what does the price tag say in the window?

The amount that the price tag says is calculated as:

£24 + £6

= £30

The amount that the price tag says is £30

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
