Question

5) which term of AP 56, 50, 44, is first negative? With solution​

Answer 1

Step-by-step explanation:

$here \: a = 56 \\ d = 50 - 56 = (- 6)$

56 ÷ 6 = 9(6) + 2

therefore when we divide 56 with 6, 2 is the remainder so the a⁹th term will be 2 more than 0.

now we hve to again subtract 6 from 2 so we will get -4 and this the first negative term in this AP
