Question

find the 10 term of an AP 2,4,6,8 using nth formula
​

Answer 1

Step-by-step explanation:

from the given AP

a=2

d=a2-a1

d=4-2

d=2

for the 10th term

An=a+(n-1)d

a10=2+(10-1)2

a10=2+9(2)

a10=2+18

a10=20

hence tenth term of AP is 20

Answer 2

Answer:

Step-by-step explanation:

nth term=tn=a+(n-1)d

2,4,6,8

first term=a=2

common difference=d =4-2=2

10th term=t10=2+(10-1)2

10th term=2+(9)2

10th term=2+18

10th term=20
