Question

4. Find the 15th term of the arithmetic progression 10, 4, -2,​

Answer 1

Answer:

here

a = 10

d = -6

t15 = a + (n-1)d

t15 = 10 + 14(-6)

t15 = 10-84

t15 = 74

Answer 2

Answer:

-74

Step-by-step explanation:

given AP - 10,4,-2

a=10

d=4-10 = -6

General Formula : an=a+(n-1)d

=> an = 10+(15-1)*-6

=> an = 10+14*-6

=> an = 10+(-84)

=> an = -74

Therefore, the 15th term of the AP 10,4,-2

is -74
