Question

Find the multiples of 7 lying between 300 and 700

Answer 1

Step-by-step explanation:

Ap=301,308,315......700

a=301

d=a2-a1

=308-301

=7

an=700

n=?

an=a+(n-1)d

700=301+(n-1)7

700-301=(n-1)7

399=(n-1) 7

399/7=(n-1)

57=(n-1)

(n-1)=57

n=57+1

n=58

the multiple between 300 to 700 is 58
