hey guys PLZZZZZZ NEEDDDDDD URGENT HELP!!!! EXAM TOMORROW

give me any HELP ME WITH SEQUENCE

TELL ME ANYTHING THAT COULD HELP ME TO SOLVE ANY SEQUENCE QUESTION NO MATTER HOW HARD IT IS PLZZZZZZZZZZZZZ

Learn these 2 formulas:

1) This formula can only be applied if the difference is constant between the first and the second, second and third etc.
nth term = a + d (n - 1)
where:
'a' is the FIRST term
'd' is the DIFFERENCE between the terms


2) This formula can only be applied if, in simple terms, the first term is multiplied by a number to get the second term... and the second term is multiplied by the same number to get the third and so on:
nth term = ar^(n-1)
'a' is the FIRST term
'r' is the number they are being multiplied with
1, 2, 4, 8, 16 (for instance)
1*2^(n-1)
= 2^(n-1) Answer


There are many questions you can't solve even when you know these sequences. For that, you need to use some common sense and the sequences already given

It's easy:
h inverse (x) = x
h inverse (x) = 2
x = 2

Put x=2
h(x) = 3^x
h(x) = 3^2
h(x) = 9

------------------
can you plz give more explanation

 

[always-smile :)]

can anyone plzz give more explanation... the exam is after 3 hours
