Question

Two arithmetic progressions has the same common difference. If the first term of the first progression is 3 and that of the other is 8, then the difference between their 3rd term is
a) 2. b) 3
c) 4. d) 5​

Answer 1

Step-by-step explanation:

in first progression a¹=3

in second progression a²=8

third term generally is written as a3=a+2d

|a¹3-a²3|=a¹+2d-a²-2d

=|a¹-a²|

=|3-8|=5
