A=-1.25,d=-0.25 write first four terms of AP,when first term a and 'd'are given as follows |
Answer» Given:
To find:
Solution:From the question, we are provided with the values of a and d. Since, we know that a means first term of an A.P,
Still we need to find three terms. We know that, → d = Second term - First term → Second term = d + First term → Second term = (-0.25) + (-1.25) → Second term = -0.25 - 1.25 → Second term = -1.5 Similarly, → d = Third term - Second term → Third term = d + Second term → Third term = (-0.25) + (-1.5) → Third term = -0.25 - 1.5 → Third term = -1.75 Finally, → d = FOURTH term - Third term → Fourth term = d + Third term → Fourth term = (-0.25) + (-1.75) → Fourth term = -0.25 - 1.75 → Fourth term = -2 Hence, the four terms of A.P are -1.25, -1.5, -1.75 and -2.
