Question

Does the sequence -1,-1,-1,-1........ forms an AP

Answer 1

$\LARGE\underline{\mathcal{\purple{A}\green{ɴ}\pink{s}\blue{ᴡ}\purple{ᴇ}\green{ʀ}\pink{★}}}$

ʏᴇs, ᴛʜᴇ sᴇǫᴜᴇɴᴄᴇ 1,-1,-1,-1........ ғᴏʀᴍs ᴀɴ ᴀᴘ

ᴄᴏᴢ,

$d = a _{2} - a_{1} = - 1 - ( - 1) = - 1 + 1 = 0$

$d = a_{3} - a_{2} = - 1 + 1 = 0$

$d = a_{4} - a_{3} = - 1 + 1 = 0$

value of d is same

following sequence forms an AP
