Mean = 23
=> (21 + 16 + 24 + x + 29 + 15) / 6 = 23
=> ( 45 + 16 + x + 44) = 23 * 6
=> ( x + 105) = 138
=> x + 105 = 138
=> x = 138 - 105
=> x = 33
=> (21 + 16 + 24 + x + 29 + 15) / 6 = 23
=> ( 45 + 16 + x + 44) = 23 * 6
=> ( x + 105) = 138
=> x + 105 = 138
=> x = 138 - 105
=> x = 33

Mean = (sum of terms)/no. of terms
23 = (21+16+24+x+29+15)/6
23*6 = 21+16+24+x+29+15
138 = 105 + x
138-105 = x
x = 33
23 = (21+16+24+x+29+15)/6
23*6 = 21+16+24+x+29+15
138 = 105 + x
138-105 = x
x = 33
