Question

Which number will be the 14th number in the sequence -10,-7,-4,-1?

Answer 1

here sequence and series concept is used....a=first term

d=difference between two consecutive terms

n=number of term

T=value of that term having number'n'!

Answer 2

It can be done by the formula

the formula is :-

tn = a +(n-1)×d

in this Formula

a =-10 as it is first number

d is difference between numbers

n is the term which we want to find =14

now SOLUTION

tn =a+(n-1)d

t14 = -10+(14-1)×3

t14 =-10+(13)×3

t14=-10+39

t14=29

So

the answer is

the 14th number in sequence is 29
