Question

Find the nth term of the A.P. – 10,- 15, -2, -25​

Answer 1

Answer:

Tn= -5-5n

Step-by-step explanation:

A.P.= -10,-15,-20,-25,....

d= -5 a=ti= -10

Tn = a+(n-1)d

= -10+(n-1)*-5

= -10-5n+5

= -5-5n

Answer 2

Answer:

a = -10 , d = -5

an = a + (n-1)× d

an = -10 + (n-1)× -5

an = -10 - 5n + 5

an = -(5n + 5)
