Question

Three consecutive terms of an A.P are respectively 3t-1,3t+5and 5t+1.Find t.

Answer 1

3t+5 answer is wrong ya right I don't know

Answer 2

Answer:5

Step-by-step explanation:The form of AP is a-r,a,a+r. So,

=3t-1 = a-r

=3t+5=a

=5t+1=a+r

=3t-1=3t+5-r

3t gets cancelled on both the sides

=-1=5-r

=-1-5=-r

=-6=-r

Therefore r=6

We know that a= 3t+5

r=6

=a+r=5t+1

=(3t+5)+6=5t+1

=3t+11=5t+1

=11-1=5t-3t

=10=2t

Therefore, t=5
