To find the common difference, we use the formula
where
<em>a2</em> represents the second term and <em>a1</em> represents the first term.
So plugging the second term and first term into
the formula, we have (17) - (12) which is 5.
So the common difference of
this arithmetic sequence is 5.
First add plus 5 to -5 and 22. Then -5 cancels outdo now u have 3b=27. Divide 3 to 3b and 27. Then you will have b=9
Step-by-step explanation:
Let the length be L.
Let the breath be B.
So, we are given that
length of a rectangle is 7 inches greater than three times its width .
So, according to the Question,
L = 7+ 3B.
So, we know that:-
Area = Length× Breadth.
So, it will be
B × (7 + 3B) = Area.
So,
3B² + 7 is an expression to represent its area.
