Question

For the following A.P., write the first term and the common difference.

$0.6,1.7,2.8,3.9\dots$

Answer 1

Calculate the common difference:

The given series $=0.6,1.7,2.8,3.9\dots$

We know that the common difference,

$d=a_2-a_1$

For the given series, $a_1=0.6$ and $a_2=1.7$

$\therefore d=1.7-0.6$

$=1.1$

Hence, the first term is $0.6$ and the common difference between this series is $1.1$.
