Question

write first four terms of the AP
a=20,d=50​

Answer 1

Answer:

20, 70, 120, 170

Step-by-step explanation:

First term = a = 20

Common difference = d = 50

Second Term = First term + Common Difference

                       = 20 + 50

                       = 70

Third term = Second term + Common Difference

                  = 70 + 50

                  = 120

Forth term = Third term + Common Difference

                  = 120 + 50

                  = 170

Hence, first four terms of AP are,

20, 70, 120, 170
