<span><u><em>The correct answers are:</em></u>
A, B and C.
<u><em>Explanation</em></u><span><u><em>: </em></u>
<u>A parallelogram</u> is a quadrilateral with both pairs of opposite sides parallel.
<u>A rectangle</u> is a parallelogram with all right angles, so yes, every rectangle is a parallelogram.
<u>A square</u> is a parallelogram with all right angles and all congruent sides; since it is a parallelogram with all right angles, every square is a rectangle.
<u>A rhombus</u> is a parallelogram with all congruent sides.
Since a square is a parallelogram with all congruent sides, then every square is a rhombus.
<u>A </u><u>trapezoid</u> is a quadrilateral with one pair of parallel sides. Since a rhombus is a parallelogram, with 2 pairs of parallel sides, rhombus are not trapezoids.</span></span>
The expression for nth term is:
a_n = -5+4n
Further explanation:
Given sequence is:
-1,3,7,11
We have to determine first if this is a arithmetic sequence or geometric sequence
The sequence is an arithemtic sequence if the common difference of cosecutive terms is same.
In this case,

As the common difference is same the sequence is an arithmetic sequence
Standard form of arithmetic sequence is:

Putting the values of a_1 and d

The expression for nth term is:
a_n = -5+4n
