Show that the sequence 9, 12, 15,18 is an AP. Find it's 16th term and the general term ?

57

Step-by-step explanation:

Ok so if I can remember it goes this way

Find the common term:

12-9=3

18-15=3

Common term: 3

Take the first number of the sequence: 9

First number of sequence + common term * the term you want

9+3*16=57

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
