Question

a=12 d=4 an=76
find n​

Answer 1

Answer:

17

Step-by-step explanation:

using

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

using the given values,we get

76 = 12 + (n-1)×4

(n-1)=(76-12)/4=16

n = 16+1

n=17

Answer 2

$\huge\dag\maltese{\underline{\underline{\boxed{\bf{\red{AnSwEr}}}}}}\maltese\dag$

Here, a = 12,d = 4, an = 76, n = ?

So, an = a + (n - 1)d

76 = 12 +(n - 1)4

76 = 12 + 4n - 4

76 = 8 + 4n

4n = 76 - 8

n = $\frac {68}{4}$

n = 17.
