Answer 2

given,

first term(a)= 3

last term(L) = 27

common difference (d) = ?

fifth term from the last formula = L - (n-1)d

fifth term from the first= a + 4d

fifth term from first = fifth term from last ......... { given }

solution........

a + 4d = L - (n-1)d

3 + 4d = 27-(5-1)d

3 + 4d = 27- 4d

4d+4d = 27-3

8d. = 24

d. = 24/3

d. = 8
