Question

in an ap : a3 = 3 a10= 10 find a15
please help me​

Answer 1

hi good morning all the best

Answer 2

Answer:

15

Step-by-step explanation:

a+(n-1)d=a3

a+(3-1)d=3

a+2d=3 (i)

Similarly,

a+(n-1)d=10

a+(10-1)d=10

a+9d=10 (ii)

On subtracting both equations

7d=7

d=1

Substituting the value of d in (i)

a+2×1=3

a+2=3

a=1

a15=a+14d

a15=1+14×1

a15=1+14

a15=15

hope it helps..
