Answer:

95

Step-by-step explanation:

We need to add up by 3 from 50 until we get the 15th number so we do this:

1. 53

2. 56

3. 59

4. 62

5. 65

6. 68

7. 71

8. 74

9. 77

10. 80

11. 83

12. 86

13. 89

14. 92

15. 95

The 15th term is 92.

What is an Arithmetic Sequence ?

A sequence of numbers where each number is linked with its consecutive term by a fixed number is called Arithmetic Sequence.

It is given that

The test score results are

50 , 53 , 56 , 59 , 32 ..................

The common difference is 3

Then the nth term is given by

Tn = a₁ + (n-1)d

a₁ is the first term = 50

n = 15

Then the 15th term is

T₁₅ = 50 + (15-1) * 3

T₁₅ = 92

The 15th term is 92.
