Analyze the following pattern 1,2,5,10, describe the pattern can someone me with my apex

First differences start at 1 and increase by 2.

Whenever analyzing any sort of sequence, it is usually helpful to look at the differences between terms. Here, they are ...

... 1, 3, 5, 7

This set of numbers clearly increases by 2 from one to the next. That is, second differences are 2.

When 2nd differences are constant, the pattern can be described by a 2nd-degree polynomial. In this case, that is

... n² -2n +2 . . . . for n = 1, 2, 3, ...

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
