Answer:
832
Step-by-step explanation:
Sum of n terms of an AP is
= n/2[ 2a + (n-1)d ]
n = number of terms , a = first term , d = difference between two consecutive terms
Here n = 16 , a = 7 , d = 13 - 7 = 6 .
THEREFORE The sum of 16 terms of the AP
= 16/2 [ 2(7) + (16-1)6 ]
= 8 [ 14 + (15)6 ]
= 8 [ 14 + 90 ]
= 8 [ 104 ]
= 832
THEREFORE THE ANSWER IS 832 !
