Asequence has 3 terms its term to term rule is multiply by 6 and then add 13
a) the first term of the sequence is -2
workout the third term
b) the order of the three terms of the sequence is reversed
describe the term to term rule of the new sequence

a) Third Term = 19

b) Term to Term rule = Subtract 13 and then Divide by 6

Step-by-step explanation:

a)

Since first term is -2, so according to rule, second term is:

second term =

Now, finding the third term with the rule:

Third Term = 19

b)

The first 3 terms of the sequence is -2, 1, 19 ...

If reversed, it is:

19, 1, -2 ....

The rule will also be reversed. So it will be to subtract 13 and then divide by 6.

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
