Question

please answer my question ​

Answer 1

1) The given AP is: 3,1,-1,-3,...

Thus, First term=3 (a1)

Second term=1 (a2)

Thus, common difference = a2-a1 = 1-3= -2

2) The given AP is: -5,-1,3,7,...

Thus, First term=-5 (a1)

Second term=-1 (a2)

Thus, common difference = a2-a1 = -1-(-5)= 4

3) The given AP is: 1/3, 5/3, 9/3, 13/3,...

Thus, First term=1/3 (a1)

Second term=5/3 (a2)

Thus, common difference

= a2-a1 = 5/3-1/3= 4/3

4) The given AP is: 0.6,1.7,2.8,3.9,...

Thus, First term= 0.6 (a1)

Second term= 1.7 (a2)

Thus, common difference

= a2-a1 = 1.7-0.6= 0.11
