Answer 1

Heya

The common difference is -4

Seventh term is 4

an = a + (n-1)d

4 = a + (7-1) (-4)

4 = a - 28

4+28=a

a=32

The first term is 32

Hope it helps! ^_^

Answer 2

Hi Friend

Here's ur ans :-

Common difference ( d ) = - 4

Let first term be a

Given a7 = 4

n = 7

• an = a + ( n - 1 ) d

4 = a + 6 × ( - 4 )

4 = a - 24

4 + 24 = a

28 = a

So, first term is 28
