Answer 2

Answer:

96

Step-by-step explanation:

In this given series:

32,45,60,77,?

we have to get the 5th number

Comparing all four numbers we get

$32=32\\45=32+13\\60=45+15\\77=60+17$

so the next number is the sum of the first number and an athematic series in which the first number is 13 and 2 is   the common difference between terms

putting formula

$a_{n} = a_{1} +d(n-1)$

$a_{n}$=the nᵗʰ term in the sequence

$a_{1} =$ the 1st term in the sequence

$d=$the common difference between terms

$a_{4} =13+2(4-1)$

$a_{4} =19$

adding 19 with forth number of series

$=77+19\\\\=96$

Answer is 96
