For the following A.P.s, write the first term and the common difference.
i] `3, 1, -1, -3, … `
ii] `-5, -1, 3, 7, …`
iii] `(1)/(3) , (5)/(3), (9)/(3) , (13)/(3) , ….`
iv] `0.6, 1.7, 2.8, 3.9, ..`

Text Solution

Verified by Experts

The correct Answer is:
i] `a= 3, d = 1 - 3 = -2.`
ii] `a= -5, d = -1-(-5) = 4.`
iii] `a= (1)/(3) , d = (5)/(3) -(1)/(3) = (4)/(3)`.
iv] `a= 0.6, d = 1.7 - 0.6 = 1.1.`
