Question

givena=5,d=3,an=50 find n?​

Answer 1

Given :-

• First term (a) = 5
• Common difference (d) = 3
• $\sf\:a_n=50$

To find :-

• $\sf\:n^{th}\:$term of Ap

Solution :-

an = a + (n - 1) d

50 = 5 + (n - 1) × 3

50 = 5 + 3n - 3

50 = 3n + 2

50 - 2 = 3n

48 = 3n

48/3 = n

16 = n

n = 16

Hence , nth term of Ap is 16
