Question

write frist four terms of the A. P, when the first term a and the common difference d are given as follows? a) a=10 , d = 10 , please can guys answer me step by step OK​

Answer 1

Answer:

Given: a = 10 and d = 10

The general form of an A.P is a, a+d, a+2d, a+3d,…

So, the first term a is 10 and the common difference d is 10, then the first four terms of the AP is

10, (10+10), (10+2×10), (10+3×10)

⇒ 10, (20), (10+20), (10+30)

⇒ 10, 20, 30, 40

Hence, first four terms of the A.P. is 10, 20, 30 and 40.

hope it helps you

please mark me as brainliest

Answer 2

Answer:

An arithmetic progression is given by a,(a+d),(a+2d),(a+3d), .

where a= the first term, d= the common difference

10,10+10,10+2(10) and 10+3(10)=10,20,30 and 40
