Question
Write first four terms of the AP, when the first term $a = -1.25$ and the common difference, $d = –0.25$
✓
Answer
Here, $a_1= a = -1.25, d = -0.25$
First term, $a = -1.25$
Second term, $a_2= -1.25 + d = -1.25 + (-0.25) = -1.50$
Third term $= -1.50 + d = -1.50 + (-0.25) = -1.75$
Fourth term $= -1.75 + d = -1.75 + (-0.25) = -2.00$
Hence, first four terms of the given AP are $-1.25, -1.75, -2.00$
