Question

write the first four term of the AP when the first term 'a' and the common difference 'd' are given as follow:a=10,d=10
​

Answer 1

Answer:

Step-by-step explanation: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.
