Here is your answer user.

Step-by-step explanation:

$\large\boxed{\fcolorbox{cyan}{blue}{Given}}$

Tn = 5n-4.

S4= ?

Taking,

Tn = 5n-4.

Case 1------ T1 = 5(1)-4

= 1.

Case 2------ T2 = 5(2)-4

= 6.

Case 3------- T3 = 5(3)-4

= 11.

Case 4 ------ T4 = 5(4)-4

= 16

Putting the value case (1,2,3,4)

S4 = (1+6+11+16).

= 34.
