Step-by-step explanation:
A rhombus is a four-sided geometric figure, which has the main characteristic that these four sides are equal to each other. They generally have a diamond shape, with four vertices pointing towards the four cardinal points.
The square, for its part, is a special type of rhombus, where not only its four sides are equal but also its angles, since they are four right angles.
F(n)=a1+(n-1)b
f(20)=33+(20-1)11
f(20)=33+(19)11
f(20)=33+209
f(20)= 242
