Question

The average of first 50 multiples of 4

Answer 1

Answer:

102

Step-by-step explanation:

The first 50 multiples of 4 form an AP with

first term ( a ) as 4, common difference ( d ) as 4 and number of terms ( n ) as 50

last term = a + ( n - 1 ) d

=  4 + ( 50-1 ) 4

= 4 + 49 ( 4 )

= 4 + 196

= 200

finding sum of first 50 multiples of 4...

= 50 / 2 ( 4 + 200 )

= 25 x 204

5100

average of first 50 multiples of 4 = ( sum of first 50 multiples of 4 ) / 50

= 5100 / 50

= 102
