We know that what ever n=1 results in we get the common difference. Next we know that the 7th terms is 28. What can we say about the seventh term? It is 7 times the 1st term. So 28/7=$t_{1}=d$

#

then how are u solving this question

#

it says

#

arithmetic sequence

#

kk

#

so uk right

#

tn = a + (n-1)d

#

write equations using this

#

ull get it
