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 ;)
