Question

The 30th term of top 3, 10, 17 is
of

a) 97 b) 7 c) 90 d) none of these
​

Answer 1

Answer:

3 , 10 , 17

here, a = 10 , d1 = 10-3 = 7 , D2 = 17-10 = 7

since, d1=d2. means this is an AP

so,

first term (a) = 3

common difference (d) = 7

nth term = a + (n-1)d

30th term = 3 + (30-1)3

= 3 + 87

= 90

Hence, option (c) 90 is the correct answer..
