Question

The 20^( th ) term of an A.P,0.1 0.4 ,0.7 ,1.0..... is ............... (a) 8.5 (b) -8.5 (c) -5.8 (d) 5.8​

Answer 1

The 20^( th ) term of an A.P,0.1 0.4 ,0.7 ,1.0..... is 5.8

Answer 2

Answer:

Here a = 0.1

d = 0.4 - 0.1 = 0.3

so, 20th term = a + 19d

= 0.1 + 19 × 0.3

= 0.1 + 5.7

= 5.8

so option (d) is correct
