Question

determine the terms of the following APS as follows :
10th term of 1,4,7,10...​

Answer 1

Answer:

determine the terms of the following APS as follows :

10th term of 1,4,7,10...

1,4,7,10,.....

first term of this A.P is  a1=1

second term of this A.P is  a2=4

 common difference of an A.P is given by

(i.e.,d=an+1−an)

putting n=1 in above equation

d=a2−a1=4−1=3

hence common difference for this A.P is d=3

the nth term of an A.P is given by.

an=a1+(n−1)d

hence, for calculating 10th term of A.P a10 put n=10 in above equation

a10=a1+(10−1)d

a10=1+9×3

a10=1+27

a10=28

Answer 2

Answer:

a= 1

d= 4-1

=3

nth term = 10

By formula,

a+(n-1)d= 1+27

=28
