State Converse of Basic Proportionality theorem
Find the first term and common difference of the progession 1,3/2,5/2,..​

Answer 1

Answer:

If a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side.

Step-by-step explanation:

In a series of terms, is each term exceeds the preceding term by a constant, the terms are said to be in arithmetic progression which is also known in short term as AP.

Here, the arithmetic progression are :-

1, 3/2 and 5/2 are the arithmetic progression.

First term, a1 = 1

Common difference, c.d. = a2 - a1 = 3/2 - 1 = 3 - 2 / 2 = 1/2

.°. common difference, c.d. = 1/2

.°. First term, a1 = 1 ANSWER
