Question

For each sequence find the first 4 terms and the 10th term n Squared + 3

Answer 1

Answer:

4, 7, 12, 19 and 103

Step-by-step explanation:

Substitute n = 1, 2, 3, 4, 10 into the n th term formula, that is

1² + 3 = 1 + 3 = 4

2² + 3 = 4 + 3 = 7

3² + 3 = 9 + 3 = 12

4² + 3 = 16 + 3 = 19

Thus the first 4 terms are 4, 7, 12, 19

10² + 3 = 100 + 3 = 103

Thus the 10 th term is 103

Answer 2

Answer:4, 7, 12, 19 and 103

Step-by-step explanation:

Substitute n = 1, 2, 3, 4, 10 into the n th term formula, that is

1² + 3 = 1 + 3 = 4

2² + 3 = 4 + 3 = 7

3² + 3 = 9 + 3 = 12

4² + 3 = 16 + 3 = 19

Thus the first 4 terms are 4, 7, 12, 19

10² + 3 = 100 + 3 = 103

Thus the 10th term is 103
