690-180-258=252
230 × 3= 690
690-180-258=252

Average score required = 230.
Score in first match = 180
Score in second match = 258.
Let score in third match be X
Average = sum of all observation ÷ number of observation.
Therefore
230 = (180 + 258 + x ) ÷ 3
230 × 3 = 438 + x
690 = 438 + x
Therefore
x = 690 - 438 = 252.
Therefore the cricketer will need to score 252 runs in the next match.
