Question

Given a=5,d=3,an=50 find n and s​

Answer 1

Answer:

answer for the given problem is given

Answer 2

Answer:

Given a = 5 , d = 3 , an = 50

= a + ( n - 1 ) d = 50

= 5 + ( n - 1 ) 3 = 50

= 5 + 3n - 3 = 50

= 3n = 50

= n = 16

S 16 = 16 / 2 { 2a + ( 16 - 1 ) }

= 8 { 2 × 5 + 15 × 3 }

= 440

Therefore ;; n = 6 , s = 440
