Question

Write first four terms of the $AP,$ when the first term $a = 10$ and the common difference $d = 10$.

✓

Answer

$a = 10, d = 10$
First term $a = 10$
Second term $= 10 + d = 10 + 10 = 20$
Third term $= 20 + d = 20 + 10 = 30$
Fourth term $= 30 + d = 30 + 10 = 40$
Hence, first four terms of the given $AP$ are $10, 20, 30, 40$
