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
