Question

Tn=2n-5 write down four term in a sequence

Answer 1

Answer:

- 3, - 1, 1, 3

Step-by-step explanation:

To find the first four terms, substitute n = 1, 2, 3, 4 into the rule

T₁ = 2(1) - 5 = 2 - 5 = - 3

T₂ = 2(2) - 5 = 4 - 5 = - 1

T₃ = 2(3) - 5 = 6 - 5 = 1

T₄ = 2(4) - 5 = 8 - 5 = 3

The first 4 terms are - 3, - 1, 1, 3

Answer 2

Answer:

Four terms will be :--3,-1,1,3

Step-by-step explanation:

Given :

Tn=2n-5

Now, putting the value of n=1,2,3,4

T(1)=2(1)-5

T(1)=2-5

T(1)=-3

T(2)=2(2)-5

T(2)=4-5

T(2)=-1

T(3)=2(3)-5

T(3)=6-5

T(3)=1

T(4)=2(4)-5

T(4)=8-5

T(4)=3
