Question

if Tn=2n*3+1 find n so that Tn=55.​

Answer 1

Step-by-step explanation:

so the value of ............n=3

Answer 2

The value of n is 3. Further explanation is given below.

Step-by-step explanation:

Given equation is:

Tn=2n*3+1

According to the question,

Tₙ=55

we have to find the value of "n". So, we can find this by putting the value of "Tₙ" in the formula which is given below:

Tₙ=2n³+1

On putting the value of Tₙ in the above formula, we get

55=2n³+1

2n³=55-1

2n³=54

n³=$\frac{54}{2}$

n³=27

n³=$3^3$

n=3
