Answer 1

Step-by-step explanation:

$\huge \boxed{ \fcolorbox{green}{silver}{good morning}}$

here's your answer:

question:

a1=-3

a5=5

to find=a10

solution:

we know that the general term of an ap is:

an=a+(n-1)d

thus, the 1st term will be:

a1=a+(1-1)d

-3=a

thus, the value of a is -3

a5=a+(n-1)d

5=(-3)+(5-1)d

5=-3+4d

8=4d

thus,the value of d is 2

now,

10th term will be:

a10=a+(10-1)d

a10=(-3)+(9)(2)

a10=-3+18

thus, the answer to your question is a10=15
