Question

in an ap the common difference (0) and seventh term (a) 154 , then find first term

Answer 1

The value of first term (a) is 154

Step-by-step explanation:

Given Data

In an Arithmetic Progression,

Common difference (d) = 0

$\text {Seventh term} (t_7) = 154$

$t_n = a+ (n-1) d$

154 = a + (n-1) d

where n = 7 (seventh term)

154 = a + (7-1) d

154 = a + 6d

Substitute the value of 'd'

154 = a + (n-1) (0)

154 = a + 0

a = 154

Therefore the value of 'a' is 154 when the seventh term is 154 and the common difference is zero.

Answer 2

First term = 154

Step-by-step explanation:

Common difference (d) = 0

$a_7=154$

$a_n=a+(n-1)d$

⇒ 154 = a + (7 - 1)d

⇒ 154 = a + 6d

⇒ = a + 6(0)

⇒ 154 = a + 0

⇒ a = 154

First term = 154
