Question

(6) Write an AP when the first term is
6" and common difference is "3"​

Answer 1

Step-by-step explanation:

a=6 , c.d=3

second term = a+d = 9

thus the ap will be

=>  6,9,12,15,18,21,--------- n

Answer 2

Step-by-step explanation:

given

first term of AP = 6

common difference = 3

basic solution for beginners:-

therefore

by the formula an = a+(n-1)d

2nd term = a2= 6+(2-1)3

= 6+3= 9

again 3rd term a3= 6+(3-1)3= 12

hence AP= 6 ,9, 12, .......................an

fast calculation:-

a= 6, d= 3

AP= 6, 6+3, 6+2×3,.....................an

= 6, 9, 12, .............................an

where AP means arithmetic progression
