The first and last term of an A. P are 1 and 121 respectively. Find the number of terms in the A. P and the common difference between them if the sum of the term is 1281​

No.of terms=21

Common difference=6

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

answer: 414,377,008

step-by-step explanation:

just multiply it
