Determine the 25th term of A. P,whose First term is -6 and common difference is 5/4"

Answer 1

Given,
First term ( a) = -6
Common difference = 5/4

We know that, nth term of A. P = a + ( n-1)d .

Now, 25 th term of A. P
= a + ( 25 -1)d
= a + 24d
= -6 + 24 ( 5/4)
= -6 + 6(5)
= 30 - 6
= 24 .

∴ 25 th term of The Given A. P is 24

Answer 2

Hey ❗❗

_____________________________________

↪a (First term of AP) = -6

↪d (common difference) = 5 / 4

↪an = a + (n-1)

↪a25 = a + 24d

↪a and d are given in the question now put values of a and d ,

↪(-6) + 24 (5 / 4) = a25

↪-6 + 6(5) = a25

↪-6 + 30 = a25

↪24 = a25

↪Hence 24 is the 25th term of AP.
