Question

If nith term of an A.P. is 6n+ 5, then
find the fifth term.​

Answer 1

Answer:

Step-by-step explanation:

substitute n=5 in given equation

we get answer

6x5+5=35

in another method

we know first term is a=6x1+5=11

d=tn-tn-1

substitute n=2 in equation=6x2+5=17

d=17-11=6

t5=a+(n-1)d

11+(4x6)=11+24=35

i think first method is easy
