Question

a=10 d=2 find 50th term

Answer 1

First term a=10

d=2

Use formula directly

an=a+(n-1)d

a50=10+(49)d

a50=10+98

a50=108

so, 50th term of this A.P. is 108

Answer 2

a= 10

d= 2

Tn = a + ( n-1 ) d

T50 = 10 + ( 50 - 1 ) 2

T50 = 10 + (49) 2

T50 = 10 + 98

T50 = 108

Therefore 50th term is 108.

Hope this helps!!
