Question

Which term of the A.P 3,8, 13, 18 is 148 ?​

Answer 1

a = 3, d = 8-3 = 5

tn = a + (n-1) d

148 = 3 + (n-1) 5

148 - 3 = (n-1) 5

145 = n - 1

5

29 + 1 = n

30 = n

n = 30

Hence 148 is the 30th term if this A.P.

Answer 2

Let the term be A(n)

a = 3

d = 8-3 = 5

A(n) = a+(n-1)d = 148

3+(n-1)5 = 148

(n-1)5 = 145

n-1 = 29

n = 30

Therefore, 148 will be the 30th term
