Question

what is the answer of this question

Answer 1

a) as we see over here A1=1^2
$a2 = {2}^{2} \\ \\ \\ similarly \: we \: get \: that \: \\ \\ a10 \: = {10}^{2} \\ \\ = 100$
$b ) = we \: get \: different \: remainders \: on \: diving \: perfect \: squares \: by \: 3$
$c) \: = {3}^{2} . {6}^{2} . {9}^{2} .... \\ squareof \: all \: those \: which \: are \: multiple \: of \: 3$
$d) \: = as \: we \: saw \: in \: the \: above \: sequence \: nth \: term \: = {n}^{2} \\ \\ \\ thus \: 10nth \: term \: will \: be \: (3 \times 10) \: whole \: square \: \\ \\ = 900$
$e) \: = the \: remainders \: will \: be \: \: 1 \: in \: all \: these \: cases.$
$f) \: = \: -24 \: . \: - 23 \: . \: ......$
