Answer:

6; 75/2

Step-by-step explanation:

nth term: 3n²/2

Second term: n=2

3(2²)/2 = 6

fifth term: n=5

3(5²)/2 = 75/2

Higher than 50:

3n²/2 > 50

3n² > 100

n² > 100/3

Since n is positive,

n > (100/3)^½

n > 5.7735

Since n is a natural number, n has to be atleast 6 for the number to be greater 50
