Question

Two AP’s have the same common difference. The first term of one of these is -1, and that of the other is -3. What is the difference between their second term?

Answer 1

Answer:

2

Step-by-step explanation:

First AP terms are a1,a2,a3,a4...

Second AP terms are A1,A2,A3....

A/q

a2-a1 = A2-A1 ------- eq(1)

a1 = -1

A1= -3

on putting these values in eq (1)

a2- (-1) = A2 -(-3)

a2+1=A2+3

a2-A2 = 2
