Question

if a=2, d=3, an=29. find n.​

Answer 1

Answer:

10

Step-by-step explanation:

29= a+ (n-1) d

29 = 2 +(n-1) 3

29-2= (n-1) 3

27/3 =n-1

9 =n-1

9+1= n

n=10

Answer 2

Answer:

$an = a + (n - 1)d \\ = 29 = 2 + (n - 1)3 \\ = = 29 - 2 = (n - 1)3 \\ = 27 = (n - 1)3 \\ = n - 1 = \frac{27}{3} \\ = n - 1 = 9 \\ n = 10$

n=10

hope it helps....❣️
