Question

In an A.P 7th term = 4 and d =-4 find firs term

Answer 1

Answer:

a + 6d = 4

a + 6(-4) = 4

a -24 =4

a = 28

therefore 1st term is 28

Answer 2

Answer:

a = 28

Step-by-step explanation:

Given in an A.P

common difference (d)=-4---(1)

Let first term = a

${n}^{th} term \: = \: a \: + \: (n - 1) \: d$

Now,

=> a + 6d = 4

=> a + 6(-4) = 4 [ from (1)]

=> a - 24 = 4

=> a = 28

Therefore,

First term (a) = 28
