Question
There are 2 APs, each having 3 terms whose common difference differ by 1. find the two APs.
1. Sum of the three consecutive terms is 15
2. P and
1. Sum of the three consecutive terms is 15
2. P and
Answer: Option E
:
E
Answer=option (e)If the three terms AP 1 = a-d,a and a+dAP 2 = A, A-D and A+D and D= d+1S= 3a = 3A= 15. a=A=5Also, P/P1= {a(a2-d2)}/ {(A2-D2)} = 7/8It is not possible to get a unique solution, even after using both statements. Answer isoption (e)
