Question

find the 10th term of AP -3, -1, 1,3​

Answer 1

Step-by-step explanation:

AP -3,-1,1,3

a=-3

d=-1-(-3)

d=-1+3

d=2

n=10

An=a+(n-1)d

An=(-3)+(10-1)2

An=(-3)+(9)2

An=(-3)+18

An=15

therefore the 10th term will be 15

Answer 2

Step-by-step explanation:

AP -3,-1,1,3

a=-3

d=-1-(-3)

d=-1+3

d=2

n=10

An=a+(n-1)d

An=(-3)+(10-1)2

An=(-3)+(9)2

An=(-3)+18

An=15

therefore the answer will be 15
