Question

is this form an A. P? find common difference and the next three terms ​

Answer 1

Answer:

AP is 1√2, 2√2, 3√2, 4√2..............

1st term = 1√2

common difference =2√2-1√2. = √2(2-1) =√2

next three terms are

5th term = a+4d = 1√2 +4×√2 = √2(1+4) = 5√2

6th term = a+5d = 1√2+5×√2 = √2(1+5) =6√2

7th term =a+6d = 1√2+6√2 = √2(1+6) =7√2

hence the AP is

1√2, 2√2, 3√2, 4√2,5√2,6√2,7√2

hope this will help u........
