#### EXERCISE

##### Type - 1
###### Question 1 :
Write first four terms of the AP, when the first term a and the common difference d are given as follows:
(i) a = 10, d = 10
(ii) a = –2, d = 0
(iii) a = 4, d = – 3
(iv)
(v) a = – 1.25, d = – 0.25
###### Formulae used :

Distance Formula to find distance between two points (x1,y1) and (x2,y2) is :                                                D = √[(x2 – x1)2 + (y2 – y1)2 ]

###### Solution :
Sol. (i) Here x1 = 2, y1 = 3, x2 = 4 and y2 = 1
∴ The required distance
