Answer 1

Answer:

15

Step-by-step explanation:

a=-3. d=2. n=10

an=a+(n-1)d

a10=-3+(10-1)2

1. -3+18

=15

Answer 2

Answer:

15

Step-by-step explanation:

Given:

n = 10

a1 or the first term = -3

d: 2

Formula

an = a1 +(n-1)d

a10 = -3+(10-1)2

a10 = -3+(9)2

a10 = -3+18

a10 = 15

The 10th term in the series is 15:

-3, -1, 1, 3, 5, 7, 9, 11, 13, 15
