Write first four terms of the AP, when the first term and the common difference
Write first four terms of the AP, when the first term \( a \) and the common difference \( d \) are given as follows \( a= \) \( -1.25, d=-0.25 \)
- A. First four terms of the given AP are -1.25,-1.70,-1.95,-2.00
- B. First four terms of the given AP are -1.25,-1.50,-1.75,-2.00
- C. Not an AP
- D. None of these
Step-by-step solution
Given first term a = -1.25 and common difference d = -0.25. The terms are: a = -1.25; a+d = -1.25+(-0.25) = -1.50; a+2d = -1.25+2*(-0.25) = -1.75; a+3d = -1.25+3*(-0.25) = -2.00. Thus the correct sequence is -1.25, -1.50, -1.75, -2.00.
