Answer 1

$Given \: number \: series : \\899,960,1023 , 1088, \red{?}$

/* Observe the series ,we can find following pattern */

$i) First \:term \\= 30^{2} - 1 \\= 900 - 1 \\\blue{= 899}$

$ii) Second \:term \\= 31^{2} - 1 \\= 961 - 1 \\\blue{= 960}$

$iii) Third\:term \\= 32^{2} - 1 \\= 1024- 1 \\\blue{= 1023}$

$iv) Fourth \:term \\= 33^{2} - 1 \\= 1089 - 1 \\\blue{= 1088}$

$v) \red{Next \:term }\\= 34^{2} - 1 \\= 1156 - 1 \\\green{= 1155}$

Therefore.,

$\red { Required \: term } \green {= 1155}$
