Question

Find A.P Which fifth term is 5 and common difference is -3

Answer 1

Hey

Here is your answer,

Given that,

A5 =5
Common difference, d = -3

An= a +(n-1)d
A5= a +(5-1)(-3)
a + 4x(-3) = 5
a + (-12) =5
a = 5+12
a = 17

AP = 17,14,11,8,5...

Hope it helps you!

Answer 2

Heya !!!



Common Difference (D) = -3




And,



5th term = 5



A + 4D = 5


A + 4 × -3 = 5




A - 12 = 5



A = 5+12




A = 17




First term (A) = 17



Second term = A + D = 17+(-3) = 14





Third term = A + 2D = 17+2 × (-3) = 11





AP = 17 , 14 , 11
