Question

10th term from AP 2,7,12....​

Answer 1

Answer:

n=10 , a= 2 , d=a2-a1= 7-2=5

A10= a+9d

A10 = 2+9×5

A10= 2+45

A10= 47

Answer 2

Given,

1st term(a) = 2

Common difference(d) = 7 - 2 = 5

n = 10

so,

an = a + (n - 1)d

= 2 + (10 - 1)5

= 2 + 45

an = 47

so,

10th term of the AP = 47
