Question

Find the mean of first 5 squared natural number .(hint x=1+2+3+4+5 / 5

Answer 1

HI MATE
WE ALL KNOW THAT NATURAL NO STARTS FROM 1 to Infinite
SO , first 5 NATURAL NUMBERS are 1,2,3,4 and 5 AND their square are 1,4,9,16 AND 25
MEAN=TOTAL SUM OF NUMBER OF OBSERAVTION / NUMBER OF OBSERVATION
THEN,(1+4+9+16+25)/5=55/5=11
SO THE MEAN OF THE SQUARE OF FIRST FIVE NATURAL NUMBERS IS 11
