we are given

we can see that
n starts from 0 and goes to 5
so, there are 6 terms
that's why this statement is false
so, true statement can be written as
The are six terms in the series equation.........Answer
5

3/3 would be your answer in exact form.
Let “n” represent the least of the odd numbers. Then the next two will be:
n + 2 and n + 4 that their sum is 159.
n + (n + 2) + (n + 4) = 159
3n + 6 = 159
3n = 153
n = 51
And to check: 51 + 53 + 55 = 159
Both the side are 21 units.
⇒ It is an isosceles triangle.

Property of the angles in a triangle:
----------------------------------------------------
Sum of all angles in a triangle = 180°
----------------------------------------------------
Find x:
----------------------------------------------------
x + x + 38 = 180
----------------------------------------------------
Combine like terms:
----------------------------------------------------
2x + 38 = 180
----------------------------------------------------
Take away 38 from both sides:
----------------------------------------------------
2x = 142
----------------------------------------------------
Divide by 2 on both sides:
----------------------------------------------------
x = 71
----------------------------------------------------
Answer: x = 71°
