Write an explicit formula for a-n, then term of the sequence 36, 39, 42,

a^n = 36 + (n-1) * 3

Step-by-step explanation:

Explicit formula for arithmetic sequences: a^n = a^1 + (n-1) * d

In this case, a^1 = 36 and common difference/d = 3

So...

a^n = 36 + (n-1) * 3 is the explicit formula for this sequence.

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
