Question

Find 2 nd and 3 rd term of the sequence whose nth term is give by tn = 2n - 5 ?

Answer 1

here is your answer..


as tn=2n-5

so, t2 = 2(2) -5

t2 = 4-5

therefore , t2 = -1

t3 = 2(3) -5

t3= 6-5

therefore, t3=1


hope this helps u....

Answer 2

Answer:

an=2n-5

a1=2*1-5

a1=2-5

a1=-3

Now a2

Putting n=2

a2=2*2-5

a2=4-5

a2=-1

Similarly a3

Putting n=3

a3=2*3-5

a3=6-5

a3=1
