t = 18/2
= 9
Sorry only thing I know is this!!
The explicit formula for the sequence is 3n -10
<h3>What is an Arithmetic Sequence ?</h3>
An arithmetic sequence is a series of terms which have common difference between its consecutive numbers.
The sequence given is
−7, −4, −1, 2, 5, …
The common difference between each term is d =3
-4-(-7) = 3
-1-(-4) =3
The nth term for a sequence is given by
Here a is the first term = -7
n is the no. of terms = n
d is the common difference = 3
Therefore the equation will be
= -7 +3n -3
= 3n -10
Therefore the explicit formula for the sequence is 3n -10 .

Hello!
Question 1
The angles in a triangle add up to 180°
Subtract the known angles from 180 to get x
180 - 105 - 40 = 35
The answer is 35
------------------------------------------------------------------------------------------------------
Question 2
The angles in a triangle add up to 180°
The box means that angles is 90°
Subtract the know angles from 180 to get x
180 - 65 - 90 = 25
The answer is 25
